Re: My plans for Bison: reentrant and pure

OK, let me back up a step.

The actual problem I have, I guess, is that I want to declare the scanner
function in my re-entrant parser in a type-safe way, not using void *.
Any day I have to use void * and casting is not a good day - it seems
like a bug that the API forces me to that.

YY_DECL is only a means to that end. Can we come uo with another way to
be type-safe that meets your concerns?

I think that would be very useful, and not just for me.
