That sounds like I must reproduce all the functions in log.py in UFL
also in FFC. If I want to do say

  info("foo")

in FFC, then if I call the info() function in UFL, the UFL logger will
be used.

Is there a way that I can reuse the functions in log.py in UFL without
needing to reimplement them in FFC?
