Bug 9419 – std.random.uniform of BigInt

In some situations I'd like to generate a random BigInt: import std.bigint: BigInt; import std.random: uniform; void main() { BigInt a = 0; BigInt b = BigInt(1) << 70; auto r = uniform(a, b); } Currently (DMD 2.062alpha) it gives: ...\dmd2\src\phobos\std\random.d(1106): Error: template std.random.uniform does not match any function template declaration. Candidates are: ...\dmd2\src\phobos\std\random.d(1104): std.random.uniform(string boundaries = "[)", T1, T2)(T1 a, T2 b) if (!is(CommonType!(T1, T2) == void)) ...\dmd2\src\phobos\std\random.d(1142): std.random.uniform(string boundaries = "[)", T1, T2, UniformRandomNumberGenerator)(T1 a, T2 b, ref UniformRandomNumberGenerator urng) if (isFloatingPoint!(CommonType!(T1, T2))) ...\dmd2\src\phobos\std\random.d(1175): std.random.uniform(string boundaries = "[)", T1, T2, UniformRandomNumberGenerator)(T1 a, T2 b, ref UniformRandomNumberGenerator urng) if (isIntegral!(CommonType!(T1, T2)) || isSomeChar!(CommonType!(T1, T2))) ...\dmd2\src\phobos\std\random.d(1255): std.random.uniform(T, UniformRandomNumberGenerator)(ref UniformRandomNumberGenerator urng) if (isIntegral!(T) || isSomeChar!(T)) ...\dmd2\src\phobos\std\random.d(1274): std.random.uniform(T)() if (isIntegral!(T) || isSomeChar!(T)) ...\dmd2\src\phobos\std\random.d(1106): ...
