[Python-Dev] Python keywords (was Lockstep iteration - eureka !)

[Bill Tutt]

The parser actually recognizes keywords atm.

We could change that so that each keyword is a token.
Then you would have something like:

keyword_allowed_name: KEY1 | KEY2 | KEY3 | ... | KEYN | NAME
and then tweak func_def like so:
func_def:  DEF keyword_allowed_name parameters ':' suite

I haven't pondered whether or not this would cause the DFA to fall into a
degenerate case or not.

Wondering where the metagrammer source file went to,
Bill

Isn't it the scanner which recognises reserved words?

In that case, just make it not do that for the next
token after certain tokens.
