If you tell me the library you wish to use I may be able
to suggest a better alternative.
I'm using FFTW and PLPlot (but not with Haskell), both
uses internal states and thus must be considered as ill
designed. Do you know of better alternatives?
I'm no expert on this, being exposed to FFTW for a couple of
hours, but isn't its internal state encapsulated into the
'plan', which is suitable as a handle?
Additional to plans it stores some "wisdom" which is handled globally.
