Slang::Mosdef
All the cool kids are using def to declare methods. Now you can, too.

use Slang::Mosdef;
class Foo {
def bar {
say 'I am cool too';
}
method baz {
say 'This is not as much fun';
}
}
You can also use lambda for subs!
my $yo = lambda { say 'oy' };
$yo();
Or λ!
my $twice = λ ($x) { $x * 2 };
say $twice(0); # still 0
Compute 5 factorial using a Y combinator:
say λ ( &f ) {
λ ( \n ) {
return f(&f)(n);
}
}(
λ ( &g ) {
λ ( \n ) {
return n==1 ?? 1 !! n * g(&g)(n-1);
}
})(5)
