So are iterators and umpteen other patterns.

I'm against. This is a sliding slope. Michael agreeing to this surprises me a bit. He was not exactly fond of when notifiers were introduced in Delphi's containertypes (which are more or less observer relations too, though less flexible) > As for the iterators idea I mentioned months ago.

Most patterns are pretty much unchanged in principle since GoF. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
