           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows

          Severity: normal
          Priority: P2

This D2 program seems correct:


import std.algorithm: map;
void main() {
    int n = 2;
    map!((double x){ return x * n; })([1.0, 2.0]);
}


But DMD 2.048 prints at run time:
object.Error: Access Violation


On IRC #D jA_cOp has commented that TDPL says that the compiler should
automatically choose delegate over function if it accesses its outer lexical
scope.
