To quote "Perl Best Practices" - "Subroutines always receive their arguments in the @_ array. But accessing them via $_,$_1, etc. directly is almost always a Very Bad Idea." See page 178
Conway goes on to say "Moreover, it's easy to forget that each element of @_ is an alias for the original argument; that changing $_ changes the variable containing that argument."
So please unpack "@_" and "chomp" the copy. Who knows the calling code might need the trailing "$/"!
