Rakudo can do custom circumfixes now to some degree:

> sub circumfix:<` `>($arg) { say "here, got $arg.perl()" }; `42`
here, got 42
> sub circumfix:<{{ }}>($arg) { say "here, got $arg.perl()" }; {{42}}
here, got 42

Trouble with the example in this ticket is that | is also a prefix
operator, and seems to win. Not sure if that's wrong or right. But
anyway, we've some basic support for this now. Given to moritz++ to
spectest the bits we have, and let's open new tickets for specific
issues that are agreed on #perl6 to get bugs.

Thanks,
