Could you be more specific about this? When I write a parser it
always starts with either
_token_re = re.compile(r'''(?x)
...15 lines omitted...
import yapps2 # wheeee!
I've never had much luck hand-coding a lexer in straight-up Python.
Not only is it slow, I feel like Python's syntax is working against
me-- no switch statement, no do-while. (This is not a complaint!
It's all right. I should be using a parser-generator anyway.)
Josiah mentioned array.array('c'). There's also array.array('u'),
which is an array of Py_UNICODEs. You can add the string methods in a
subclass for a quick prototype.
