Can i define lexer in the form of classes?

[ishankhare07]

instead of defining regex rules in individual functions with names like t_<some_name>
can't we use python classes to define these functions in, and then pass a class instance to lex.lex()?

I'm new to writing lexers/parsers as part of my course on compilers, so I might as well ask :-
Can this be done in the current implementation?
and if not, is it even fruitful and beneficial in some way?

What about something like this?
