   @pitrou @westonpace I've updated the parser to reflect the discussion on the mailing list. The language now looks like the traditional function call syntax instead of the lisp-style syntax. I've also gotten rid of the `!` needed before FieldRefs (now it's either `.name` or `[idx]`). I've kept the syntax for literals the same
   ```
   add(.a, $int32:1)
   ```
