Haskell already does this, to some extent, in the design of imprecise
exceptions. But note that bottom *does* have well defined behavior, so
these optimizations are not very desirable.

There are two primary reasons for this

Dear Haskell-cafe,
When dealing with ghc type errors I often see messages like
Couldn't match expected type `ghc-prim:GHC.Types.IO{tc 32I}
MyTypeNameHere{tc r1d8}'
with actual type `ghc-prim:GHC.Types.IO{tc 32I}

They're not *usually* desirable, but when the code has been proven not to
fall into bottom, there doesn't seem to be much point in ensuring that
things will work right if it does. This sort of thing only really makes
sense
