In the code below, x
and y
are implicitly converted to uint
and ushort
before the function preconditions are run.
Is there any way to change this behavior? It feels unintuitive and I can't find in the spec where it says when the conversions in this case occur, but it clearly happens before the preconditions are run.
import std.stdio: writeln;
void foo(uint x)
in (x >= 0)
{
writeln(x);
}
void foo(ushort x)
in (x >= 0)
{
writeln(x);
}
void main() {
int x = -1;
foo(x); //prints 4294967295
short y = -1;
foo(y); //prints 65535
}
