Oh, c'mon. This is a frequently cited yet overstated wart. Yeah,
technically it's a problem, but much more a theoretical than practical one
- in practice the only time it causes problems is when you're doing
something questionable anyway, like reusing a variable without
initializing it to some known value.

It's a nit rather than a real divergence from Haskell's list comps.
