Of course you are right. In the example of "parallel" loops It's _a_lot_ 
easier to to use for the programmer. "Lightweight-threaded" stuff like 
parallel loops was not the original aim of ThreadEvents. The original 
target was a more "standard" use of threads. But it _can_ be used for 
parallel loops, too, and it follows the "Delphi-language-paradigms" a 
lot tighter than using TThread.

I don't suppose that anybody will start implementing real parallel loops 
like suggested on the wiki page any time soon. But TEventThread and 
"Thread Events" is quite easy to do.

Sorry if I have been vague here. Of course it is (as is the alternative 
to enhancing the meaning of "of object"). But this is only another 
enhancement that can be done as a second step. Most of the functionality 
can be used (or at least tested) by just implementing TEventThread (and 
TMainEventThread) in the RTL (and maybe LCL).

Of course. But where  to add them ?

Of course you are right again: It's a good idea to do a separate page. 
I'll do that ASAP,
