this is only tangentially relevant to what op is asking for - i remember
having to do something like this to trace every function enter / exit into
a log:

func foo() {
    enter() { defer exit() }

and copy-paste that mantra at the beginning of every function. the enter /
exit would do some printing of the method name (#function) among other

it was a bit annoying manually doing so in every method, and one of course
can dream of some automated built-in facility to the same effect. until
that time, manual tricks like this will do.
