Your code is still missing 'new':
auto alg = new Algorisme!(int, int);
Unrelated recommendations:
- Return 0 from main() for successful exit, anything else by convention
means some sort of error.
- Take advantage of constructors (and 'alias') to simplify syntax and
risk of bugs:
import std.conv, std.stdio, std.stream, std.string;
import std.socket, std.socketstream;
import std.datetime;
class Algorisme(U,V) {
string nom;
uint versio;
alias V function (U) Funcio;
Funcio funcio;
this(string nom, uint versio, Funcio funcio)
{
this.nom = nom;
this.versio = versio;
this.funcio = funcio;
}
}
int main(string [] args)
{
alias Algorisme!(int, int) MeuAlgorism;
auto alg = new MeuAlgorism("Doblar", 1,
(int a) { return 2 * a; });
return 0;
}
Ali
