in thread bitwise string operator question

Thanks Abigail-II, i just learned something cool for the day:

perl -le'sub uc{@_[0]^" "};print uc($_)for(a..z)'
Can't believe i hadn't picked that up before now ...

DOH! Heh, my original one-liner did the bitwise XOR in a map ... i should know better than that. :P Let's try that again:

perl -le'sub flip{@_[0]^" "};print flip($_)for(a..z)'
There, no ambiguity now. But ... the saddest part is that i learned this trick too late. My C++ Lab students last semester had to write a function that would flip case ... i really wish i could have blown their minds with this one. ;)

    That calls the buildin uc. You might want to call ::uc instead. But beaware, it doesn't uppercase! It flips the case, uppercase to lowercase, and lowercase to uppercase.

    Also be aware that, if you're using locales and such, uc() is aware how to transform accented characters and will DTRT.
