Re: [Bayonne-devel] Problems about loop structures

[David Sugar]

In general currently used versions of libccscript do not have automatic 
stack management, hence, if one uses things like gotos or has ^events 
happen within a loop, the interpreter stack frame is not immediately 
recovered unless pop is explicitly used.  The testing branch has 
automatic stack management, where the stack is flattened for a goto or 
event handler regardless of how many frames deep in a loop one is, and 
so it generally does this very well.  Automatic stack management will 
also be part of a future libccscript distribution.
