4b0cdf9123 lang: types, engine: graph: Support pointer interfaces 
If we have rare, but special *interface{} values in resource structs, we
should be able to handle them normally. It's really not recommended that
you use these unless you know exactly why they are useful.

1c9fdc79c0 engine: util: Add a workaround for printing special resources 
This let's our tests compare strings of interface fields!

90d04990ca engine, lang: Add an AST test that looks at fields too 
This gives us more options for testing when we need those kinds of more
extensive resource examination features.

aa001ed2dc engine: graph: Improve error message for rare case 
Not sure if we ever hit this, but we should fix it up since I noticed
it.

3a3bc568b3 engine: Allow more send/recv cases 
This allows the other part of this. This still needs to be improved, but
it unblocks some use-cases.

b048b2684b engine, lang: Allow resources with a field of type interface 
This lets us add a resource that has an implementation with a field
whose type is determined at compile time. This let's us write more
flexible resources.

What's missing is additional type checking so that we guarantee that a
specific resource doesn't change types during run-time.

cb6b8a9670 engine: util: Refactor code for future changes

efc5237265 lang: types: Improve error handling of value code

cb999af653 engine: Improve debugging for invalid send/recv res 
If we don't implement send/recv properly, at least give the user more
information as to where.

long-term or not is to be decided.

ea0af4dc43 lang: parser: Add lookup functions to lexer/parser 
This seems to make things work. I'm worried I might have an ordering bug
where we might choose the wrong precedence if we write ambiguous code
somehow, but at least for now, let's commit this and move on. Hopefully
the nonassoc stuff is actually correct.

8fa5241a13 lang: funcs: Add struct lookup with an optional field 
This adds an interesting version of the struct lookup function. In the
situation where we can't type-check the field name, it will use the
optional value passed in. This makes it easy to write a function that
will pull in the desired value, even as the input struct changes type
between compilations, without having to re-write your code.

It's structurally different from the other default lookup functions,
which is why it is named differently.

e38eb43955 lang: funcs: Add core lookup functions 
These versions don't take defaults and instead return the zero value if
there is an issue.

3b46e88734 lang: types: Improve docs for New and initialize the list 
If we use this to generate a zero value, we want to make sure it's
completely initialized in case we use it subsequently. We also improve
the docs at the same time.

d6a58f33f3 lang: funcs: Add lookup default func for list or map

1dc6ebbffc lang: funcs: Fix one small typo and one small logic bug

ee1e07f3d7 lang: funcs: Rename T2 to T3 for future consistency

9e7b7fbb3a lang: parser: Define variable identifier in the parser 
Instead of in the lexer. I think this simplifies things and gives the
parser more information which should hopefully make it easier to parse
without shift/reduce conflicts.

b8f8ec8aa3 lang: parser, funcs: Take out the built-in history function 
It's a normally named function for now, until we think of a common
package to move it into.

Hopefully this makes improving the lexer and parser easier for now. We
can consider bringing it back if needed.

05d570d250 lang: parser, funcs: Change the logical operators to OR, AND, NOT 
This makes it easier to read for some, and easier to parse for us. This
also frees up more characters to use elsewhere.

ab7eb0a293 util: password: Reverse the nonblocking stdin 
It's not clear if this is absolutely necessary or not, but it probably
doesn't hurt. It's not clear if there is a way to read the previous
state before running this. Of course this isn't really thread-safe, so
use at your own risk.

01f249d484 util: password: Add a cancellable ReadPassword style functions 
It was non-trivial to do this, so I put it into a library. Strangely I
couldn't directly wrap the ReadPassword function from the
golang.org/x/term package, as it wouldn't unblock for some reason.

This is a big giant patch that implements the AST part of lambdas!

I don't know how Sam is able to understand the AST so well, but he does,
and we're all grateful for it. Most of this code was written by him.
