Could it be that monks of your experience will see almost any example as trivial, because it's something you've been doing for years?
If not, what about CGI.pm? Would you agree that using CGI.pm is less effort and more maintainable? I posit that this is a non-trivial example because it is so frequent (still!), particularly roll-your-own query-string parsing.
How about descriptive varible names? One might argue that typing $target_hostname is more physical effort than $th, but descriptive hostnames can reduce cognitive effort, and if you know your way around your editor, the physical difference can be minimal.
