Very lightweight, task-based generators.

# Generators.generate — Method.

generate(func::Function)

Create a generator from func. Func receives a "yield" function as its argument. You can use this function to produce values.

Here's an example of a recursive generator:

flattened(list) = generate() do yield
    fl(el::Vector) = foreach(fl, el)
    fl(el) = yield(el)
    fl(list)
end

[flattened([1, [2, [3], 4], 5])...] == [1,2,3,4,5]
