Yield all values from another iterator
ruby
Solution
This is probably the most idiomatic approach:
def f
yield 'a'
yield 'b'
end
def g(&block)
f(&block)
yield 'c'
yield 'd'
end
Problem
Does Ruby provide any mechanism to allow an iterator to `yield` all values from another iterator? (or "subiterator", I'm not sure what the proper name is). Similar to Python3.3+'s yield from ``` def f yield 'a' yield 'b' end def g # yield everything from f yield 'c' yield 'd' end ```
