Come to think of it, that is a problem: we don't have any way to declare
a function as taking "any tuple type". So even though pltcl or plperl
functions could be written to work with such input, we can't declare them.
This is a problem even for C functions. You could declare a C function
as taking "any", but then you can't even check that what you got was a
tuple ...
Something to work on for 7.5, I suppose.
