name mangling - prefixes

[lilkeet]

its annoying to always have to type 'cuda' or 'cufft' or whichever library you're trying to use!

some options of approach:

• c2nim - supports prefix, postfix, etc. but leads to errors otherwise not extant
• c2nim (araq-gobject) - directly supports postprocessor, possibly fixing c2nim's mangling problems. but this fork is not super convenient to set up or work with
• current pre and post processor - text based, which is annoying
