Partially a followup to my own Re^2: [Perl 6] Generalized shortcutting C<||>?: Synopsis 6 specifies the syntax to define infix, prefix, postfix, circumfix and postcircumfix custom operators. This achieves much. But there does not seem to be any means to specify more generic ones, e.g. ternary ones and I wonder if for completeness and absolute freedom it could be provided. I know that this slightly exceeds the pragmatics paradigm, but what if one wanted to create a ternary operator of the following form?

EXPR INFIX EXPR LEFT_DELIM STRING RIGHT_DELIM

One problem that I see is with canonicalization for insertion in the symbol table, but it should be mathematically feasible by abstracting a symbolic representation of the operator's structure...
