This is an extreme corner case, especially if a one-way semantic 
@property syntax is available to work around it.  The percentage of 
functions that return callables is very small, and of these the 
percentage that would forget @property is probably very small.  I'd 
rather bug-proneness in a ridiculous corner case than breaking tons of 
existing code code and losing a nice feature in the common case.

Right.  The point is that I can do the same thing with either property 
syntax or with chaining.  The choice is up to me as the caller, if the 
API designer is ok with allowing this choice.
