           Summary: CTFE fails when using std.string.format with imported
                    string enum
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

File enumfile.d
---------------

module enumfile;

enum Foo : string {
  a = "Please print me",
}


File main.d
-----------

import enumfile;
import std.stdio; //without importing std.stdio or any other package, the CTFE
error disappears
import std.string;


void main() {
  pragma(msg, "%s".format(Foo.a));
}

Compiler output:
format.d(7): Error: cannot cast a read-only string literal to mutable in CTFE
format.d(7):        called from here: format("%s", "Please print me")
format("%s", "Please print me")

The code compiles correctly when either the import for the unrelated package is commented out, or when the enum is moved to the same file.

I was looking into this again today. This problem only exists when using rdmd. Compiling using DMD v2.061 or HEAD is successful.

Okay, it is the include flag.
dmd -I. main.d
Fails with the same output as above.

BTW, the compiler output shows correctly the filename main.d and not format.d as in the first comment. I was testing locally using a file named format.d.
