Internal error on nightly due to invalid IR #51
Description
As seen on PkgEval
Internal error: encountered unexpected error in runtime:
AssertionError(msg="argextype only works on argument-position values")
Since this seems like a package issue (Cassette generating invalid IR) I'm going to disable testing of Traceur on PkgEval for now, but it'd be good to fix this of course. Please ping me when that happens so that I can re-enable testing for this packages.
