I'm feeling in need of some context. Anyone got a use case for when someone would be processing characters and NEED to know that they're caseless? Trying to convert a string of Roman Latin chars from lowercase to upper when there isn't any case to convert? Couldn't that be a no-op? If Perl knows the character is caseless why not let it DWIM?Thread Previous | Thread Next
