digitalmars.D.bugs - [Issue 16137] New: Better error message: function literal accessing


          Issue ID: 16137
           Summary: Better error message: function literal accessing class
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: jbc.engelen gmail.com

This code
class A
    int i;
    void foo()
        auto a = function() { i++; }; // Line 6
gives the error (DMD 2.071):
   foo.d(6): Error: need 'this' for 'i' of type 'int'

I think it should be improved, but I do not have a great idea for it. It think
instead of mentioning "need 'this'" it should mention something about
"delegate" or "function literal needs access to object data", ...
