Would you want to use something else for that, maybe .comb?
From the spec:
'The comb function looks through a string for the interesting bits, ignoring

I may have missed an obvious answer to this question, but has any thought
been given to allowing for variables which behave as though ever operation
on them is the hyper version of that operation? Sort of an automagical way
of redefining a LOT of operators.

We are supposedly going to be able to set a class to be
"uninheritable". Will we be able to set a single method or attribute to
be uniherited by any subclasses? Please forgive me if this is one of
the seven deadly OO sins. I haven't yet had any formal education with

It really looks like an intriguing language, with a (supposedly) very
fast runtime, (again, supposedly) beating Perl, Python, Tcl, and Java in
execution times. Unfortunately I've been unable to get it to compile
and this just jumped out at me:
class Foo {
private string|int bar;
static create(string|int newBar) {
bar = newBar;
}
}
In other words, as I understand it, you can type the variable bar as
either an int or a string.

Since Adam Lopesto asked a non-regex question, I don't feel quite as out
of place for doing the same.
This one actually came to me just the other night. Would it be possible
in Perl 6 to create "anonymous classes"? Something like:
my $foo_class = class {
method new {
thing other than a
decimal number";
A friend came up with this:
sub myint { return if $_[0] =~ /\A\d+\z/; $_[0] =~ /^(\d+)/ ? $1 : 0 }
What do you guys think?

Does the alias operator, C<< -> >>, work for C blocks too?

Where $abcd would be lexically scoped to the if block and else block,
if defined. I expect it could be used with any block statement,
since Apoc 4 demonstrates it with for, g
