Goodmorning,

No, It isn't homework ... (However, when I start asking
Java-related questions here, you could suspect me of doing
so ;-)
I was trying to make an obfuscation. And I really wanted it
to be just 1 line, using the while loop in it, would cause
problems ... because I wanted to feed the @row to a map.
Something like:

my @newrow=map hex, while('aabbccdd'=~/\w{2}/g);

(That is want I wanted but, which apparently was not possible. while
just doesn't return a row) However, using a regex apparently was a good
option. Only for one reason or the other, the first time I
tried using the @row='aabbccddeefforwhatever'=~/\w{2}/g, it
didn't work. So I must have done something wrong. That's more
or less the reason I thought it couldn't be done using a regex
... which ofcourse was pretty silly and ignorant of me ;-)

Btw. Everybody thanks for their help !!! (I almost finished
the obfuscation) and next time I'll try longer before bothering
you ;-)
