optional arguments in functions

[imendez]

I think it would be a powerful imporvement the possibility of adding optional
arguments in functions.

I propose the brackets characters ('&?') to indicate that an argument is
optional, like in the functions descriptions.
For example, If I want to create a function with the same behaviour that "Round",
I will define:

Real Redondeo(Real numRed [, Real numDec = 0])
{

Real inv = numRed*(10^{numDec);
Real ent = Floor(inv);
Real mod = (inv)%ent;
Real red = numRed-mod/(10}numDec);
red

};

where the argument 'numDec' is optional:

Real a = Redondeo(4.41);
Real b = Redondeo(4.41, 0);
Real c = Redondeo(4.41, 1);
Real d = Redondeo(4.41, 2);

In this example, 'a' and 'b' have the same value (4), 'c' yields 4.4 and 'd' returns
4.41.

Fully agree but ensuring internal date syntax could be inefficient.
