          Issue ID: 13544
           Summary: calls to std.file.FileException are idup-ing their
                    string arguments
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Windows
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: Phobos

          Reporter: bugzilla at digitalmars.com

The signature for functions like std.file.copy() takes "in char[]" so it can
be called with both mutable and immutable strings. If an exception gets
thrown, the conservative assumption is that the source may get changed
so the string is duplicated.

The problem, again, is bloat.

The solution is to add two overloads for FileException, one taking string and
one taking const(char)[].
