Are you going to say you think it should be programmed to accept only 0xffff or 0XFFFF and not both?
You can program a lexer to be case sensitive or case insensitive, or even to change case. So you can have OxFfFf, just as you can declare a float literal as 12.345f or 12.345F.
I agree. Here's the link:
