@jcosborn FYI the snippet I mentionede here #15211 (comment) isn't supposed to compile, its supposed to say (13, 23) Error: expression 'prepareTileset(parsedTileset)' has no type (or is ambiguous)

You can specify that in the test file like so:

discard """
  errormsg: "expression 'prepareTileset(parsedTileset)' has no type (or is ambiguous)"
  line: 13
"""

It works fine for me (no error) when I run the test on its own. I don't know why CI fails when it is included in megatest.

Oh, yeah sorry. You are right it should compile just fine.

type TilesetCT[n: static[int]] = int seems to make CI fail. It works fine in my own tests.
Changing it to type TilesetCT[n: static[int]] = distinct int seems to work with CI.
