[NTG-context] Defining commands in \start ... \stop

Hi,

Concerned with the answers to the [that topic](http://www.ntg.nl/pipermail/ntg-context/2014/077099.html), I was thinking if I could define a command "Exercise" with a optional argument (the "Answer").

\defineblock[question]
\defineblock[answer]

\defineenumeration[question][text={Question}]
\defineenumeration[answer]  [text={Answer}]

\keepblocks[question]
\hideblocks[answer]

Something like
\startexercise My execise ...
\stopexercise

If no more is provide, at the question does \incrementcounter[answer]
If

\startexercise{\startsolution The solution is \stopsolution} My exercise
\stopexercise

then \beginanswer and \startanswer is called.

Is it possible?

I just want to know if it's better to have \startBla...\stopBla command or \Bla{} command type?
In the case of the first, how do you define that? I did not find it here (http://wiki.contextgarden.net/Commands_with_optional_arguments)

Thanks,
Xan
