It's not that simple. Tcl, Ruby and Python all have several competing implementations, while to my knowledge nobody has even written a complete Perl 5 parser (except the one in the official Perl 5 code).
- kamaal 11y agoOne of the goals of Perl 6 is to ensure several implementations of a Perl 6 specifications should be possible.
- mst 11y agoWhile this is true, I was specifically addressing the comprehensibility of the core perl5 VM sources - so the existence of N other VMs seems orthogonal to me. Or: I agree with everything you said apart from the implication that what you said is a counter argument to what I said - it seems to me that both can be true without conflict.

AFAIK, all the viable competing Ruby implementations use the parser from the mainline implementation; parsing Ruby is notoriously hard, and parsing isn't a weak point that alternative implementations usually try to improve.
