You can do a function called for example 'log-this-function'.

You send the function you wish to log to that function, it
then does a `advice-add' :before (or :after?) the function
that's supposed to be logged and the advice function can then
have the function's name with `symbol-name' since that's
available in 'log-this-function' ...
