Note: match_all() is due to become a builtin in the next release, so the version below may or may not need renaming/deleting before it will run.<br>
Currently only searches for non-overlapped sequences, but it should be pretty obviuous how to change that, in which case the next underline will simply partially overwrite the previous, so you'll get eg "<=<==>".
