#1 Thanks, Identifier Recommendation, and Nil Parameters

[CRETX]

First and foremost: THANKS for eMVC! I've been researching on-and-off for years now how to best design UI logic for programs. MVC certainly comes up, but nothing that really addresses forms based enviroments like Delphi. I just discovered some research that denoted "Classic MVC" from a more modern MVC which accounts for
controls/widgets like Delphi....

...and then I ran into eMVC! :)

I'm still comming up to speed on it, but I do have one
suggestion (one I've already implemented in my copy of eMVC):

Now some ideas for the next release:

I personally think it would be a good ideal for the most of various identifiers in your unit, and the unit name itself, to have a prefix of "eMVC" (or "TeMVC", "IeMVC", ect), to avoid collisions with other units / patterns. I do understand why you use IObserver /IObservable for the interfaces to the observer pattern (ie make available for other uses beyond just eMVC), but I still think it would be a good idea to use the prefix(es) to avoid name polution.

The other item for future versions of your user's guide: it isnt fully clear on what/how to use the parameter for the Notify()/UpdateView() - the examples use TCommand, which indeed is a very good idea but was confusing with using TCommand for mset-to-mset communications. More importantly, unless one looks at the source code of the unit, its not at all obvious that supplying nil for the parameter for the Notify()/UpdateView() WILL RESULT IN THE UPDATES NOT OCCURING! This should be mentioned in the documentation. (I'm sure there is a reason, but I cant think of why one couldnt have a nil parameter for simple applications...)

Anyway, I know I can make both of these recommendations to my own copies, but I wanted to pass them along to you for your consideration.

Thanks for solving alot of my problems! :-))
