Function hijack on selective import

The mistake you're making is using a constraint when you should
try a specialization:
int signbit(T:Custom)(T x)
{
return 0;
}
That means to use this specialized function when T is Custom.
Now, you just need to merge the overload sets:
import std.math;
alias signbit = std.math.signbit; // this merges local signbit
with std.math.signbit
and boom it should compile and call your version.
