i don't mind random discussions.. if they are technical

anyway there are cases when mutable globals are useful, but if the
problem can be solved using local variables then rather use those
(..there is a reason why lexical scoping was invented)

in case of multitasking reentrant functions are easier to reason about
(especially in case of preemptive multitasking)

however passing around context pointers just to avoid using globals
might not be justified
