          Issue ID: 17190
           Summary: [REG2.072] isNumeric!string conflict std.traits
                    std.string
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: jbc.engelen gmail.com

Testcase:
```d
// RUN: dmd -c test.d
import std.string;
import std.traits;

void foo()
{
    static if (isNumeric!string) {}
}
```

When both std.string and std.traits are imported, dmd 2.072 and 2.073 error
with:
```
isnum.d(6): Error: std.traits.isNumeric(T) at
/Library/D/dmd/src/phobos/std/traits.d(5350) conflicts with
std.string.isNumeric(S)(S s, bool bAllowSep = false) if (isSomeString!S ||
isRandomAccessRange!S && hasSlicing!S && isSomeChar!(ElementType!S) &&
!isInfinite!S) at /Library/D/dmd/src/phobos/std/string.d(5844)
```

dmd 2.070 and 2.071 compile it fine.

I am not sure whether this is a bug or not.
Thanks,
  Johan
