but it would be nice to have a function pair (log and unlog) that does
all this:
- trace the function
- redirect the output of trace to a file too
- untrace and go back to default stderr
something like this
#+begin_src picolisp
(de log (Func)
(err (tmp "log")
(trace Func)
(pass Func) ) )
#+end_src
but this does not work unfortunately...
