CallerID is a Python call tracing utility designed to capture actual usage of a program as it runs. It should, therefore, be impervious to the usual "call tracer of a duck-typed language" drawbacks.
This is A.) somewhat a proof-of-concept; I'm not 100% sure the idea will work until I try it, and B.) designed to work closely with edgegraph.
Credit for the idea behind this utility (using Python's sys.settrace) goes to
GitHub user FloweryK, specifically the call-tracer project. Check it
