|Even better would be an implementation (in C) like:
|
|    if $_.chomp?
|       str = $_.dup.chomp!
|    end
|
|where chomp? did the initial setup for the chomp, and returned true if

This requires you have to update your document.  Is this OK for you?

Well, I'll try.  But dup removal for chomp/gsub/sub is kinda hard.
