January 17, 2017 How can I implement this in D: a variant array of varying function pointer types (diff number of args or types) | ||||
|---|---|---|---|---|

 | Z add(Z...)(Z a...) {
return a + b;
}
func[] operatorPool = [&add!int];
Variant library isn't liking that. Removing & causes another error.
Essentially I want a pool of all operators that I define, but these operators can be of differing types (which I should be able to programatically grab), and different N-aryness.

func? I mean std.variant.Variant there.

Try using `variantArray` from std.variant. see https://dlang.org/phobos/std_variant.html#.variantArray | |||
