It's the fact that enforce is lazy which prevents inlining (which really does 
need to be fixed or enforce is going to continue to be a performance problem).

However, this suggestion is clearly bad, because it's suggesting turning an 
exception into an assertion, which is _very_ broken thing to do. Assertions 
and exceptions are two _very_ different things and should be treated as such.
