[Discuss-gnuradio] Loops in the flow graph

[Alberto Trentadue]

Hello
I've seen on the archives, and experienced myself, that GR does not support 
having loops in the flow graph.
I would like to get some more insight on this limitation to understand 1.the 
reasons for it and 2. how to workaround 
it in those cases where a feedback loop is a key solution.
Naively, I try asking if it would be acceptable to detect the presence of at 
least 1 sample delay in the loop and 
apply a kind of initial condition (or simply a 0 initial value) to boot the 
computations.
Where in the code the loop detection is implemented?

Thanks in advance
alberto
