Hi,
I would like to propose adding the "last" statement
to the "grep", which currently doesn't work:
maas34: perl -e 'grep { print and $_ == 3 and last } (1,2,3,4,5)'
123
Can't "last" outside a loop block at -e line 1.
This way it would be possible to use such constructs:
print_header

That's because .NET attempts to address real-world issues.

I've been recently looking over the specification for C# and the .NET
platform (and falling for very little of the verbage: almost every line of
the first chapter of book I'm reading contains at least one oxymoron), and

At least RFC 199, and several related threads
such as "$a in @b".

It's so mysterious, the land of tears.

It's inelegant only because the slice doesn't know how to tell the
iterator it only needs one value. If it did know, you'd call it
elegant. :-)

I've mumbled about it on and off. I'd like to be able to do:
$foo = new Bar;

I personally am a big fan of Obliq semantics.
It's something I'd really like to see in perl.

Taking a page from JavaScript, it would be nice in the same vein to be
able to access the "context" (stack frame type context, not scalar/list
type context) of a method, either running or not.
The idea is that if the information was available, a module could start
multiple threads, spawn them acr

Yes, but only becase .NET is a VM, not because it's from MicroSoft.
The basic goal is to have a Perl VM that can sit easily on other VMs,
whether .NET's or Java's or our own. Another example of competing

Because you might have a wantarray situation that expects no values?

suggests that assigning to a sized busy array from a lazy array will
fill it and stop.

It's certainly a mistake to say "the goals of .NET", as if
they were a monolithic whole.
But the point is, some of the (technical) goals of .NET are
worthy, if not the slightest bit original; and so it should
not be a shame if some of Perl6's goals were collinear
with them. And I hope that ends
