I have to agree with Limbic~Region - we do try to give helpful answers if the answer is already specced and/or well understood. As it is the nature with evolving languages that's not always the case.

If there is some feature not yet implemented (built-in functions would probably be easiest) that you want to see - go ahead and write it

I'd like to point out that (since June 25th) you can also implement operators in Perl 6 in Rakudo, with only marginally more effort. To get the right precedence and associativity you should still register it in src/parser/grammar-oper.pg, but the actual implementation can be done in pure Perl 6.
