[Haskell-cafe] Converting a Constraint to Bool

[Miguel Mitrofanov]

It's a bad idea. See, even if a constraint is not satisfied, there is no reason why it can't be satisfied later, in another module. So, inclusion of another module might change the behaviour of the code that was already compiled.

I'm sure that after some oleging you'd find something that is more or less similar to what you want, but it's still a bad idea.
