[Scilab-Dev] SEP: Object oriented programming under scilab

[ycollet at freesurf.fr]

Thanks for these infos.
And what about adding the following rule in the parser:
if typeof(x) == 'constant' then call the 'naked' function (without %....)
else call %.....

For OO programming, we just need to overload operators and functions  
for user defined type ...
