Almost every Perl 6 implementation implements their parser using Perl 6 regexes(partly because it's much more difficult to properly support the extensible grammar otherwise), which are essentially PEGs.

Alternately, you can implement such context-sensitive features in another pass after the parse.

I use "variable" to mean "binding" exclusively. > Sure, but it's not like immutable bindings are required for that, just go the internal iterator route and you're set for most cases. Right. That's why in my first comment, I said that no

There are certainly other potential issues with closing over mutable variables. However, if Python's variables were immutable, it would have to create a new scope for the for body(either with statement-level scopes or by using internal iter

by ekiru 16y ago
The real issue is that Python's for construct doesn't create a new lexical scope for the body. In either Perl 5 or Perl 6, both of which use mutable variables, the corresponding code does the right thing (although Perl 5 only does so if you

Why isn't that a good thing? That criterion would cause you to dismiss Haskell because it looks different from what you're used to; the example code in the link is quite similar to Haskell code. The most useful programming languages to lear

Better than either of those, I think, would be allow url("your-url-here") (with reject or something similar for the opposite). You could even drop the url method and simply write allow "your-url-here" if you only need to allow

If a programmer writes code that is that bad in Perl, they will write code that is that bad in Python. They will write code that is that bad in C or in Ruby or in Haskell. No language will make programmers who don't care about good code to

How is this so? Decorators are just syntactic sugar for defining a function then replacing it with the result of calling another function (the decorator) on it.

vim was released in 1991. emacs did exist 30 years ago, but it's certainly evolved quite a bit since then. My personal emacs installation evolves regularly, although I will admit that it hasn't evolved at all today.

Perl 6 would do that like this: @employees.grep($predicate1 & $predicate2 & $predicate3); The predicates can be a function, a regex, a type, or anything that can be smart-matched against. Alternately, if you want to get the employee
