Yes and no.
It provides a moderately good container for data on the Perl side of things, but thats about it. PDL::PP just wasn't cut out for the job I want to accomplish.
PDL::PP is really good at making rich, perlish interfaces.
However, since I'm generating the glue, I'm adhering to the principle of least surprise. That entails making all things coming from Fortran "feel" like they would in Fortran.
For example, in F9x calling a non- pure sub with an array that has too many dimensions is illegal. But calling a pure sub with an array with to many dims should thread. In F77, the array should be flattened.
As far as I can tell, PDL::PP can only do the second of these.
There are other issues with things like type-coercion messing up overloading.
