The main problem I see with case-insensitivity is the fact that there
are always
more than one way to do it, as it depends on charset _and_ locale ;(
For example 'Ä'=='ä' in my locale but not in US, not to mention that in
some
locales even the character count may change when going from upper to
lower case.
So I suspect that only valid reason for case-insensitivity is
compatibility with
arbitraryly-case-altering OS-es, like the ones Microsoft produces.
For any other use WYSIWYG field names should be preferred.

I guess the best place would be sobewhere very near lexer.
You could also try just uppercasing anything outside ''/"" even before
it is
passed to backend.
