Comment (by rwbarton):
This code relies on the monomorphism restriction since if `bounds` is
generalized, there is nothing determining its type at its use in the
subexpression `(Ix.rangeSize bounds)`.
What might be confusing is that `:set -XFoo` affects the language
extensions used when ''loading'' files in ghci. You probably want to use
`:seti` in your `.ghci` file, which affects the language extensions used
when evaluating expressions interactively.
