Note from THE FUTURE: in PDL 2.040 in April 2021, "native complex" data (with types cfloat or cdouble) worked properly, eliminating the 0th "real or imaginary" dimension. That then made the x operator work in standard PDL with native complex numbers. Around the same time, PDL::LinearAlgebra and PDL::FFTW3 were made to also work with "native complex" data, allowing it to be used with those fast C/Fortran libraries.
