Yes, that is in ghc-options and therefore only does something when you
compile; it's not consulted at runtime (indeed, running a program
doesn't
even look at the cabal file).
Not really. -with-rtsopts is a linking-time flag that sets the default
RTS options.
Oh, I think I misunderstood what you're saying. You were pointing out
that Alfredo didn't recompile his program. I thought you're saying that
this isn't supposed to work at all.
Right. I considered mentioning the distinction between compile-time and
link-time, but as cabal-install doesn't expose such a distinction it's
pretty pointless. Maybe I should have said "build" instead of "compile"
though.
