Does ci offer a call stack

[eluser]MyDarkPassenger[/eluser]
Is there a way with ci to find the current call stack at a point in the program along with the inputs that get passed to each function? For example if I have a user class with a setName function I'd like to be able to call a function in setName and get something like the following:

class function argument line type
main index 6 controller
user setName "gene" 4 model
