Should_yield (is it needed?)

I have the code working for this but I wanted an opinion on making a
patch.

I sometimes have the need to expect that a method will yield a block
it’s
given. Usually this means something like this:

yielded = false
subject.method { yielded = true }
yielded.should == true

which is a bit tedious and ugly. My solution might be just as ugly, but
I
wanted to get feedback because it saves that tedious code.

subject.method(&should_yield)

I wrote a few methods, that when called, return an object with #to_proc
that
expects that the proc is called (or not called). I have the following
forms
available fairly simply:

subject.method(&should_not_yield)
subject.method(&should_yield_with(object))

# Expects 3 yields, one with each argument
[1,2,3].each(&should_yield_each(1,2,3))

I think this is a little cleaner and the code is very simple. I wanted
to
get an opinion on whether this is worth making into a patch.
