Re^2: Polish Prefix Calculator

[protist]

I edited the reformat subroutine so that it now properly handles the input you described. Thank you for pointing out that bug. :)

I can see no reason to not (italics) use ~~

Whenever I put $num in that particular line of code, it would store $4 in $3 for some reason. Eventually since I already had it written and working, I decided to not fix what wasn't broken. Maybe I'll change it later.

I removed the useless (?:) groupings you described. It is worth mentioning that my regex for verbose contains redundancies, but intentionally so for the sake of being explicit.

I like your eval join part, but I think you will find the parsing this problem requires is much more involved than tr/()//
