           Summary: CFTE fails in non-template and functions that takes no
                    args.
           Product: D
           Version: 1.006
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: kevinbealer at gmail.com


In the following code, I think A, B, C, and D should work, but only A works. 
If B, C, or D is uncommented, an error is reported during compilation.  I'm not
sure if this is one or more bugs, but at the moment the CFTE stuff seems to
require the called function to take parameters and also to be called from a
template.  (I'm guessing this has to do with constant folding working
differently in different contexts.)

char[] two()

struct A(T) {

}
