A multi sub presents only an MMD interface, while a multi method presents
both MMD and SMD interfaces. In this case, there's not much point in the
SMD inteface since .. used as infix is always going to call the MMD interface.

If you just say "multi" it defaults to "multi sub". We can theoretically
have "multi rule" if you declare parameterized rules, though most rules
take the same argument list. A set of "multi macro" would presumably
dispatch at compile time, but it's not clear how the various "is parsed"
rules would interact.
