saveing/loading symbol table of annymous functions

[David Bateman]

Looking at how to read matlab dot-mat files with anonymous function
handles in them, it seems that these files contain the local symbol
table of the anonymous function. Octave also stores these in
tree_anon_fcn_handle, as the octave saving/loading of anonymous function
handles are in ov-fcn-handle.cc, we don't have access to the local
symbol. This is true both for loading and saving the symbol table.

Can the symbol table be moved from the tree_anon_fcn_handle class to the
octave_fcn_handle class? What else does this imply? If it is moved it
would then by possible to save the symbol table of the function handle
and reload it, as well as implementing the loading of function handles
in matlab files..

D.
