YAP6: A p5 approach to p6
chromatic has made a couple of good points. But, I think he has missed the most important point of all and the very reason why anything other than Parrot will, more than likely, be unable to run Perl6 in all it's glory.
Perl6 isn't a language. It's a runtime lexically-scoped grammar engine. There is a default language being defined and that is being used to drive the vast majority of features that the VM will need to be able to provide. But, and TimToady has said this very quietly on a number of occasions, CP6AN is expected to contain a number modules that will extend (and reduce) the grammar in a lexical fashion. He has even gone so far as to say that Perl6 is really a family of languages with a primary language that everyone generally talks.
Let me drive it home - the Inline:: modules will, in most cases, be implemented as grammars on top of Parrot. They will not, as is the case right now, be implemented as call-outs to other compilers. Will YAP6 be able to handle that?
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
