          Issue ID: 24656
           Summary: enums with explicit EnumBaseType incorrectly matching
                    multiple overloads.
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: dave287091 gmail.com

The following code fails to compile due to matching multiple overloads, which
shouldn’t be correct.

```
import std;
void foo(ubyte x){
    writeln("foo(ubyte)");
}
void foo(byte x){
    writeln("foo(byte)");
}

enum E: ubyte {
    A = 0,
    B = 1,
    Z = 255,
}

void main(){
    ubyte a = 1;
    byte b = 2;
    foo(a); // ok
    foo(b); // ok
    foo(E.Z); // ok
    foo(E.A); // matches both foo(ubyte) and foo(byte)
}
```
