Muya dosen't work in Safari?
Muya doesn't work in Safari:
SyntaxError: Invalid regular expression: invalid group specifier name

It seem that Safari doesn't support lookbehind yet.

I dev and test muya on Chrome, and have not test it on Safari.
It doesn't work on Gnome Web (formerly Epiphany) either (which also uses WebKit)

I also tested it on Falkon and Konqueror and they both work.
Here are some specs from https://www.whatismybrowser.com/ of, from left to right, Konqueror, Gnome web, and Falkon :

Webkit browsers hurt my brainnnnnn
Safari should now support regular group names? Other issues are welcome
