This notion of "anytypename" is utterly unworkable anyway; there's no
way for the parser to know soon enough that a given argument position
needs to be read as a type name rather than a normal expression.
You could conceivably make it work with the argument being a regtype
literal (ie, quoted); but that seems at least as klugy as what hstore
is doing.
