Case insensitive tokenization / Flex's %option caseless

[pablosichert]

Flex has a directive %option caseless to lex tokens in a case insensitive way.

Is there currently a way (besides using regular expressions) to accomplish the same?

At the moment, no. I think before we added this, we'd need to add the idea of lexerkinds to lrlex (in the same way that lrpar has the idea of grammarkinds), because caseless is a Flex extension that isn't supported by lex. That would be a nice little project for someone to add.
