Actually I wrote it as map first and, of course, it didn't work because s// doesn't return the modified string. Breaking the unwritten rule of grep seemed slicker than:

map {s/.../.../ge; $_}

[download]
which still hides side-effects inside map or: 
map {(my $x= $_)=~s/.../.../ge; $x}

[download]
which just, well, isn't slick. :)
