Me too! I really hope Embarcadero succeeds. They’re definitely on the right track with the 2009 version.

I’m using Delphi for almost 9 years !
Nothing is impossible with this great tool.
The new RAD Studio edition is really really a good product. I really hope that Embarcadero will lead Delphi back to it’s glory road.

You could use Castalia for inline variable declaration. They’ve been improving the IDE pretty well though, so perhaps this nice feature will be in a future versions:

Good question!

In your example the prefix is hard coded in the log function. If you’d like another log function with a different prefix you’d have to create another function. Additionally, the code that utilizes your log interface is bound to that particular log function.
In my example I can easily create a different (prefixed) log function dynamically and have the utilizing code invoke it without change.
Of course the same effect can be achieved with a nice object oriented approach, (or even with your approach and a global prefix variable) but the purpose of this post was not to show how to create a prefixed log function…

I just don’t get it. What’s wrong with doing it this way???!

procedure Log(AMsg: string):
begin
WriteLn(‘Closure Test: ‘,AMsg);
end;

begin
Log(‘Write this’);
Log(‘And this’);
end.
The above program should produce the following output.

Closure Test: Write this
Closure Test: And this

There’s always pros and cons with everything. I can’t decide which way of declaring variables (at the top, in the body, or not at all) is better. It depends. And I embrace them all.

I agree with you on the help system, but that, on the other hand, is the only thing I miss from the Delphi 6 IDE.

Good question! But you’re slightly off when it comes to the reasons you listed.

My point is that it feels like Delphi has finally turned a decline in both quality and interest with the 2009 version.
Of course one can develop fantastic applications without anonymous methods, that can be done in any language, but the thing is, adding these features send the signal that Delphi is a live and evolving language. And, for a language that supports the functional paradigm (along with the object orientation) closures is a natural and useful construction.
