Wouldn't removing `unsafePerformIO` just force us, in many
cases, to write the same thing in C and then import it? Or
would you amend the FFI so "math.h sin" could not be imported
There are plenty of bad ways to use `unsafePerformIO`, this is
true; but as we already have a tool for binding to native code
in a way that trusts it to be pure, I don't see how having a
way to bind to nominally side-effecting Haskell code in a way
that trusts it to be pure adds anything to our troubles.
