Perl has it's own highlighter, specialized for Perl only. Rubby uses general (common) highlighter what is used for tens of user languages. I can't break functionality by adding new feature.
I see the symbols in Ruby are quite complicated. It similar as in all other interpreted languages what are expanded of new functionality what wasn't planned in the begin. I will try what I am able to do. -- <https://forum.pspad.com/read.php?2,74180,74187> PSPad freeware editor https://www.pspad.com
