Unicode has APL characters, so create the operators using them.

If there is a conflict with an existing feature you could always create a Slang. A Slang is a module that changes the parser. (It could be argued that with this feature all programming languages are a subset of Perl 6)

I've heard that quote, but realistically, that would be a huge project to write an efficient APL in P6 and as I already said, the performance wouldn't make you happy.
