It turns out that some planned additions to the parser make it so that
the map type definition can be ambiguous. As a result, this patch
updates the definition so that the map definition is not confused with
an open curly bracket anywhere.
Thanks to pestle and stbenjamin for their help understanding yacc!
This patch adds a simple function API for writing simple, pure
functions. This should reduce the amount of boilerplate required for
most functions, and make growing a stdlib significantly easier. If you
need to build more complex, event-generating functions, or statically
polymorphic functions, then you'll still need to use the normal API for
now.
This also makes all of these pure functions available automatically
within templates. It might make sense to group these functions into
packages to make their logical organization easier, but this is a good
enough start for now.
Lastly, this added some missing pieces to our types library. You can now
use `ValueOf` to convert from a `reflect.Value` to the corresponding
`Value` in our type system, if an equivalent exists.
Unfortunately, we're severely lacking in tests for these new types
library additions, but look forward to growing some in the future!
The test for gometalinter got silently broken in an earlier commit.
Look for the missing space that was added back in this commit to see
why! In any case, this now fixes some of the things that weren't
previously caught by this change.
If anyone knows how to run these sorts of tests properly so that entire
packages are tested and so that we can enable additional tests, please
let me know!
It's also unclear why goreportcard catches a few additional problems
which aren't found by running this ourselves.

This is an initial implementation of the mgmt language. It is a
declarative (immutable) functional, reactive, domain specific
programming language. It is intended to be a language that is:
* safe
* powerful
* easy to reason about
With these properties, we hope this language, and the mgmt engine will
allow you to model the real-time systems that you'd like to automate.
This also includes a number of other associated changes. Sorry for the
large size of this patch.
