in thread parsing a txt file

OK, from perlop:

If you don't want it to test the right operand till the next evaluation, as in sed, just use three dots ("...") instead of two. In all other regards, "..." behaves just like ".." does.

Not really sure what the difference is, so I'll stick with my normal two dot approach.
