Thanks.
after I modified f1 and f2 (attached; Matlab

the same line)
Oops.
It looks like the private function is loaded the first time it is used
and then also cleared by the "clear functions" command. But then it
also remains available through the handle. So I'm wondering whether
the handle should retain a reference to the function and "clear
functions" should only remove it from thh symbol table, or whether it
should be reloaded if it becomes invalid. I'm thinking the first
option would be best unless someone knows of a reason to do otherwise.
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 ?
