In complicated scripts, its a big effort tracking function calls to understand just whats going on. When you're trying to code for effeciency, you need detailed function calling and timing information. The ticks thing is a step forward, but it doesnt have any context information.

I'm requesting two things. The first is a ticks variant on the function level. You can register a function that gets called on every function call (and maybe another on every function exit). Its important that the callback is supplied with at least the function's name, so it can recognize the context. Supplieng it with arguments would be a plus.

The second thing would be exposing the function call stack, so you could see the caller of the current function, and its caller, all the way to the top. Being able to retrieve the time the function was called (in msecs) would be very good, but could be expensive.
