digitalmars.D.bugs - [Issue 14817] New: copy("foo", "bar") std.algorithm/std.file conflict


          Issue ID: 14817
           Summary: copy("foo", "bar") std.algorithm/std.file conflict
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: phobos

/////////// test.d ///////////
import std.algorithm;
import std.file;

void main()
    copy("test.d", "test2.d");

C:\...\std\algorithm\mutation.d(315): Error: cannot modify immutable expression

C:\...\std\file.d(2781) conflicts with std.algorithm.mutation.copy!(string,
string).copy at C:\...\std\algorithm\mutation.d(297)

This is a regression because previously the invariant of
std.algorithm.mutation.copy apparently did not accept (immutable) strings as a

This broke building Digger (along with issue 14765).
