I like the way you can add extra arguments to agent calls.
And i miss it when i use C++.

Is there anyway to emulate this eiffel features with C++ templates ?

I can bet you can't!

I don't know C++ myself enough, but Qt implemented Signal/Slots using an
additional pre-processor. Agents allow you to build the same mechanism ;-)

The README file said
"Requires Windows 95, NT 4.0, or better."
So... I installed it on Linux!

You lose your bet.
You can use function objects.

And gtk-mm did it without a pre-processor.

I have used the Boost Functor class and I think that's what you mean here
(at least in general). C++ Templates are AFAIR Turing complete, so you can
do a lot with them, but usually things end up being very very complicated
to use - especially if you make a small mistake and have to cope with page
long error messages that talk only about the templated classes, not where
you used them wrong.

Anyhow, till now I didn't see a mechanism that would allow curying
(which was the original question, and which is supported by agents).
Can you give me any pointers?


best regards,
Andreas

No I can't. I missed that bit. I apologise to Phillipe - he wins his bet.
