Add Enumerable#to_h(&block)

This is inefficient. You should create a Hash, call each and assume it's a tuple and add that to the hash.

[Sija]

@asterite spot on, fixed.

[asterite]

I think instead of U you can use Tuple(X, Y) forall X, Y and use those types to initialize the Hash.

[Sija]

I was thinking of that but then it would have to be Array(X | Y) | Tuple(X, Y).

[asterite]

Why Array? Tuple is enough. If you have an Array as the block value the caller can always convert that to a duple. Enforcing tuple guarantees a minimum level of performance.

Fair 'nuff, pushed an update.
