Comment (by thoughtpolice):

 I've fixed the clash between `-o` and `-dynamic-too`, so now when you say:

 {{{
 ghc -dynamic-too Main.hs
 }}}

 the inferred file names should be appropriately generated. The rule is
 that if you're specifying `-o` but not `-dyno`, then the `-dyno` name
 should simply be the same filename, but with the dynamic object extension.
 (Note this doesn't affect linking executables - `-dyno` has no effect
 there.)

 I'm now looking to finish the other half (enable `-dynamic-too` if we
 detect `-XTemplateHaskell` during module loading,) but my first-try patch
 doesn't seem to work yet.
