Re^6: How to de-reference a coderef?

in thread How to de-reference a coderef?

I'd like to see this, namely as in my head I can only imagine the syntax of...

my $sub = Sub sub { my $x = shift; print $x };

Being that I thought { } was the anonymous hash composer. I'm really curious about this though, and syntax reduction in general. Writing things that act like Ruby/Groovy blocks is kind of ugly when you have to use the sub keyword all of the time.

Well, a trivial implementation of `Sub` is `sub Sub (&) { return shift }` [download] but that doesn't do the blessing and overloading. You'll get to use the syntax of: `my $s = Sub { print +shift } $s->('hello');` [download] just as I indicated before. -- Randal L.
