pl.lexer is very useful indeed and I'm planning on using it for a new module. I've had to patch it to meet my needs as identifiers in the grammar I want to parse can consist of a few extra characters than specified in the IDEN pattern constant.

I added a setter to change the IDEN: lexer.set_pattern("iden", "^[%%@#$%w][%%@#$%w]*")

It seems like a reasonable requirement to be included in the base.

That looks like serious swearing! Yes, a good idea.
