This one's been around for ages, but has just now started bothering me enough to file a bug report:
import std.math;
void main() {
uint num = 1;
auto ans = sqrt(num);
}
Error:
test.d(5): Error: function std.math.sqrt called with argument types:
((uint))
matches both:
std.math.sqrt(float x)
and:
std.math.sqrt(real x)
I guess the solution is to make long and ulong overloads that forward to std.math.sqrt(real x).

Partially unrelated: an efficient D compiler can desire to implement the sqrt with SSE instructions like SQRTSS RSQRTSS SQRTPS and RSQRTPS, that have floats or doubles in input or output. So I think a double sqrt(double) too can be useful, to avoid the useless argument passing of 10-12-16 bytes (necessary for an argument of type real) for the computation of sqrt on a double.

Fixed SVN.

Still there, or crept in again.
