On further reflection, I think I would only be in
favour of 'yield *it' if it permitted an optimisation
allowing it to run more efficently than an explicit
for-loop.

In the absence of any such optimisation, writing the
for-loop out explicitly seems preferable. Not only
does it make it perfectly clear what is being done,
it avoids hiding the cost of the for-loop behind a
deceptively compact piece of syntax.
