NameType is only really needed in the parser, so this takes it out of NameDef, meaning that later passes defining names no longer need to set an arbitrary NameType for them. The parser gets slightly more complicated (because some productions now have to return a SpecType and a NameType too), but lots of other code gets simpler. The code that removed free names was the only thing outside the parser using NameType, and it now makes a more sensible decision based on the SpecType. Since unscoped names previously didn't have a SpecType at all, I've added an Unscoped constructor to it and arranged matters such that unscoped names now get a proper entry in csNames. Fixes #61.

-- | This file has tests for various Rain passes. The tests are quite nasty to look at.
|
|
-- They usually consist of a hand-constructed AST fragment that is the input to the test.
|
|
-- The expected output is either a resulting AST, or a check on the items matched in the pattern.
|
|
-- This stuff is all built on top of the Pattern system, which you can find more about in the
|
|
-- Pattern, TreeUtils and TestUtils module. Briefly, it is an easy way to match an actual test
|
|
-- result against an expected pattern, that may have special features in it. See the other module
|
|
-- documentation.
|

|
|
-- TODO document each test in this file.
