Those are going away.
Yeah, I thought as much, which is why I wasn't going to start on them :)
Perl people hate them as much as you do--the only time they're used now is to make deliberately hideous code, and hardly anyone will seriously lament the passing of that ability. No more "change the starting position for subscripts", no more "change all RE matches globally", and so on.
I don't really hate the features, I just don't use them, and wouldn't want them in Python :-) I do actually program Perl, and will do a lot more of it in the next couple of months at least (I switched projects at work, to one that will entail Perl programming roughly 80% of the time) -- I just like Python a lot more. Your comments do lead me to ask this question, though (and forgive me if it comes over as the arrogant ranting of a Python bigot; it's definately not intended as such, even though I only have a Python-implementors point of view.) What's going to be the difference between Perl6 and Python ? The variable typing-naming ($var, %var, etc) I presume, and the curly bracket vs. indentation blocking issue. Regex-literals, 'unless', the '<expression> if/unless/while <boolean exp>' shortcut, I guess ? Those are basically all parser/compiler issues, so shouldn't be a real problem. The transmorphic typing is trickier, as is taint mode and Perl's scoping rules.... Though the latter could be done if we refactor the namespace-creation that is currently done implicitly on function-creation, and allow it to be done explicitly. The same goes for the variable-filling-assignment (which is quite different from the name-binding assignment Python has.) I don't really doubt that Perl and Python could use the same VM.... I'm not entirely certain howmuch of the shared VM the two implementations would actually be using. Is it worth it if the overlap is a mere, say, 25% ? (I think it's more, but it depends entirely on howmuch different Perl6 is from Perl5, and howmuch Python is willing to change.... Lurkers here know I'm agressively against gratuitous breakage :) -- Thomas Wouters <thomas@xs4all.net> Hi! I'm a .signature virus! copy me into your .signature file to help me spread!
