executionContexts

The point here is surely a practical one.
RR have built executionContexts into the language for their own  
purposes, having written the IDE in transcript/revolution (eating  
their own haggis, as they put it), and presumably they needed it for  
some aspect of writing an IDE.

Assuming that they put it in there with the expectation that they may  
need to change the way it works, or even what it does, they chose not  
to include it in the general documented description of the language.

We are all free to use it, but RR have no responsibility to ensure  
that it will work as we expect in future, unlike the documented  
features of the language, which they must be very careful of changing.

We all have bought Revolution, and all versions, AFAIK, 'contain' all  
sorts of things to which we do not have access, and wouldn't expect to.


Best,

Mark
