Feature proposal: `raise`/`throws` function

[Diegovsky]

Given lambda's lack of complexity, it may me surprising to learn that you can't raise an exception directly. However, it is possible to create a function that receives an exception and throws it, like so:

from toolz.functoolz import excepts

def throw(exception: Exception) -> Any:
    raise exception

validation_list = ['10', '20', '30', 'invalid']
validated_list = map(excepts(ValueError, int, lambda _: throw(ValidationError(...)), validation_list)

I believe this is a good candidate for inclusion on the functoolz module. What do you think?
