Don't you lose the PP threading for the OtherPar PDL *?

Sorry I missed the first iteration. You want something like the $T
macro, which will substitute source code snippets depending on the
$GENERIC type. But by the time you see the PDLs they will have been
coerced to a common type, in a vanilla PP routine. I suggest passing
the second argument in as an OtherPar of type PDL *. Then you can
examine its type explicitly with a switch statement and do what you want.

I don't think it can be done in one PP routine but I can
implement the overload sub so that it uses power for the
non-integer exponent cases and ipow for integer exponents.

I would like to implement integer exponentiation support for ** that
is used when the exponent is an integer data type. Unfortunately, I
can't figure out how to conditionalize the code so that pow is called
for float type exponent but ipow is called for integer type
exponents. The generic type info is for the result of the operation
as a whole and not helpful here.
Suggestions?
