But the real point is that they were parsed as identifiers, *not*
keywords, and therefore have already been through a locale-dependent
case conversion.  (Look at what happens in scan.l after
ScanKeywordLookup fails.)  Unless we can undo or short-circuit that,
it won't help to apply a correct ASCII-only comparison.

Possibly we should change the parser's Ident node type to carry both the
raw string and the downcased-as-identifier string.  The latter would
serve the existing needs, the former could be used for keyword matching.

I think these are the same thing.
