Bug 4340 – Arithmetic impossible with const BigInt

This program: import std.bigint; void main() { const BigInt a = 1; const BigInt b = a + 1; } gives this: test5.d(6): Error: template std.bigint.BigInt.opBinary(string op,T) if ((op == "+" || op == "*" || op == "-" || op == "/" || op == "%") && is(T : BigInt)) does not match any function template declaration test5.d(6): Error: template std.bigint.BigInt.opBinary(string op,T) if ((op == "+" || op == "*" || op == "-" || op == "/" || op == "%") && is(T : BigInt)) cannot deduce template function from argument types !("+")(int) test5.d(6): Error: template std.bigint.BigInt.__ctor(T : string) does not match any function template declaration test5.d(6): Error: template std.bigint.BigInt.__ctor(T : string) cannot deduce template function from argument types !()(_error_) This is due to the opBinary being non-const in std.bigint.

Dupe of bug 4301 ?
