That's an interesting problem... since one of the things I like about
CMs is the ability to turn pretty much any block of code into a context
manager by substituting a yield statement at the appropriate point, not
having the ability to skip the yield is actually something of a hole in
the design.

This will need a bit of python-dev discussion, and may even turn into a
PEP (assuming we do go ahead with adding a SkipBlock exception and
modifying the with statement to check for it being raised by __enter__()
methods).
