[Haskell-cafe] RFC: "Native -XCPP" Proposal

[Dan Doel]

vector generates a considerable amount of code using CPP macros.

And with regard to other mails, I'm not too eager (personally) to port that
to template Haskell, even though I'm no fan of CPP. The code generation
being done is so dumb that CPP is pretty much perfect for it, and TH would
probably just be more work (and it's certainly more work to write it again
now that it's already written).
