           Summary: Cannot assign to delegate during definition
           Product: D
           Version: 0.173
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: marsell_pk@yahoo.com


This compiles:
  void delegate() y;
  y = { ... };

This does not:
  void delegate() y = { ... };

For example:
  void main() {
  //      void delegate() y = { return; };
        void delegate() y;
        y = { return; };
        x(y);
  }

  void x(void delegate() y) {
    y();
  }

Not sure it's a bug, that error is because of syntax conflict with struct initializers (http://www.digitalmars.com/d/struct.html). It's a limitation that might or might not be fixable, I dunno. (It does seem possible for the grammar to differentiate

Meanwhile, a workaround:
  void delegate() y = ({ return; });

The only cases parseable as either a struct init or a function/delegate body are

{ }
{ { } }
{ { { } } }
and so on.  Otherwise, it's obvious whether a { ... } contains expressions or
statements.
