Or is this a joke? In any case where is a good place to look for example code on source filters? Christian

Because source filters are:
1) Relatively new (5.005 IIRC, but I could be mis-remembering)
2) A bloody pain in the neck to write
Lots of things could use 'em if they were easier to do. That's one of the
goals of perl 6, I think.

So why do we have to do
$ip1=$i+1;# my pdl pet peave
$f->slice("(0),$ip1,$i");
instead of
$f((0),$i+1,$i); # substitute your favorite syntax here
?
Must be source filters have problems? My guess is it's possible but a
lot of
work? Or is it ?

That's sort of on the list of things to allow (I think Damian RFC'd it) but whether it happens depends on the resulting parse speed. Hardcoded parsers seem to run faster than more dynamic, extendable ones, so it might cost too much. OTOH, parse speeds might end up being a trivial part of the total program load/compile time, so it might not matter. Regardless, you can already do this in perl 5, and will undoubtedly be able to do it in perl 6, with source filters.

Access to the perl6 parser
IMHO if the perl6 core only allow access to the parser, than a module can do just about anything including all of those things proposed in RFC 115 - 117. Maybe this is an over simplification, but it seems that if the statement: use Python; caused the subsequent source to go through my Python::parser subroutine, my module could do just about anything (including parse Python!?) So the question is - does such an RFC exist for perl6 and is it's scope as broad as my imagination makes it out to be? If so need we ask for anything else?If not, why not? Jim
