A common task I've coded is to run multiple implementations of the
same function head-to-head to profile their effectiveness. An example
would be a competition in which each of two implementations provide a
response for each match. The usual way in other interpreted languages
is to have the implementers write a source file implementing the same
function prototype (same name, arguments, and return type). You load
each one in their own namespace and run each for each match.
Is there a way to load the functions in two .sci files so that the
second does not clobber the first. I can find no system for qualifying
function names or creating namespaces in Scilab. The files can not be
run in-place (without persisting in the session) since the exec()
function only loads the functions and does not run any. Using
statements outside of any function does no good as additional function
definitions might be required in the file to implement their algorithm.
I've thought of using exec() on one file, qualifying the loaded
function names with <unique competitor name>_<function name> with
assignments and clearing the original function variables (which works
manually), and doing the same for the second file but I can find no
way of getting a list of functions loaded by the last exec().
I'm either missing something really obvious or am stymied. Any help
would be greatly appreciated.

I am not sure that I truly understand your problem, but maybe what
follows can be helpful if you can run your two implementation sequentially:
- functions are first class citizens in scilab which mean you can copy
them like normal variables:
myfunc=sin;
disp("myfunc(pi/2)="+string(myfunc(%pi/2)));
myfunc=cos;
disp("myfunc(pi/2)="+string(myfunc(%pi/2)));
Could this be used to solve your problem by renaming the implementation
to test on the fly?
