Michael and Sebastian thought about it yes (data binding to controls), but
nothing was implemented back then as far as I know (and this was long
before Lazarus existed). It's only after Michael saw how I implemented and
used the Model-GUI-Mediator design pattern (which heavily uses Observer) in
tiOPF, that he modelled his code on that. The code Michael and I would like
in the RTL is very similar to what is in tiOPF's MGM.

Check your emails dated 2009-03-15 titled "Lazarus, DB controls, Observers
and Mediators".

Anyway, observer is one small example with huge potential, but the trend
still holds - most of what I want to contribute is simply shot down. But
lets not stray the subject of this thread again.

Oh like Macro's idea of creating your own RTL is a better solution. Yeah right.

No point in wasting my time implementing something that will not be
accepted. So now I discuss first.
