Here's another test to run to see whether keeping a reference to the 
function in the handle will be compatible with Matlab behavior:  unpack 
the attached file and execute the following commands in Matlab:

cd fh-bug
fh = f1
fh()         %% should display "foo-i-hithere: 1"
f2           %% should display "foo-i-hithere: 2"
clear functions   %% what will happen with persistent value in "gg"?
fh()         %% does this display "... 3" or "... 1"?
f2           %% does this display "... 1" or "... 2" or ?
