[angr] inter-function-level

Thanks for your quick response.

My vote is: call_depth is better than inter_function_level,  and 
max_call_depth is better than call_depth :-).

I assume the call tree depth, in this context, refers to the depth of 
the "dynamic" call tree associated with the VFG analysis, and if no 
max_call_depth is specified, then no such limit is imposed. Right?
