This is a known problem.  The feature you are requesting is a
relatively recent addition to Matlab, and a significant departure from
previous scoping rules.  Fixing this problem is on the long list of
other things that would be nice to fix.

If you would like to help, patches are welcome.

This topic should go in the FAQ.
