Custom operators in Rakudo
Permanent link
Last night Patrick Michaud implemented a few nice features in Rakudo: you can now refer to operators by their sub names, define custom operators and overload existing operators.
It comes with a few caveats (precedence levels and associativity are not yet implemented, and some operators that are parrot primitives don't work too well as subs), but all in all it's very nice to see this in action:
sub postfix:<!>(Int $x) {
[*] 1..$x
}
say 5!; # 120
"Rakudo: every day a bit more Perl 6". Thanks to all who contributed so far!
