           Summary: enum x = CustomType; should be a syntax error
           Product: D
           Version: D2
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: kennytm gmail.com



Currently (v2.052) it is possible to do

-------

struct Bar {    // Bar can be a struct, a class, a union or an enum.
    int x;
    int y;
}

void main() {
    enum z = Bar;      // <------
    auto w = z(1, 2);
}

-------

The effect is the same as 'alias Bar z;'. However, the RHS of an 'enum'
statement should only accept an AssignExpression, not a custom type. Either the
D compiler should reject this, or the spec should be clarified to allow this.

In 2.042 this was a syntax error. http://ideone.com/BNcSh

Looks to me like a semantic, not syntax, error.  It can't be a syntax error,
because that would cause it to fail if Bar is the name of a compile-time
constant.
