          Issue ID: 24762
           Summary: @nogc false positive error
           Product: D
           Version: D2
          Hardware: All
               URL: http://dlang.org/
                OS: All
            Status: NEW
          Severity: major
          Priority: P3
         Component: dmd

struct S { int m; }
  string m() { return "m"; }
  @nogc void f() {
      S s;
      auto x = __traits(getMember, s, m()); // Error: `@nogc` function `nogc.f`
cannot call non- at nogc function `nogc.m`
  }

Of course, this can be worked around with:

    enum M = m();
    auto x = __traits(getMember, s, M);

But the m() call is in compile-time, and should not relate to the runtime @nogc
enforcement inside f().
