Automatic Equation and Inequation evaluation.

[Carlos]

I'm interested in this kind of functionalities; Does D have
something on this ?

I thought about something like a "eval" function that would use
specified algorithms.
something likes this

import std.stdio, std.math, std.eval;

void main()
{
eval(Real; a+b^^x+c=56){
algor.brute(&result);
        }
writeln("Positive value is : ", result);
}
