This PR addresses #285

The following additions/changes were made:

Removed an extra <iostream> header, probably introduced during debugging.
Added effect_one and effect for void lambdas.
Added get that returns a maybe for extracting values.

Oh, thanks! ^^

Added effect_one and effect for void lambdas.

Perfect. :+1:

Added get that returns a maybe for extracting values.

This will play together really nice with the new monadic (fluent) interface for maybe from the other PR. (E.g.: some_variant.get<int>().get_with_default(42)). :100:
