Not sure I see why you would want to turn off execution for only some functions.
What happens if your function calls some other function with
side-effects? How would you roll that back? How would you mark
functions for the general case?
Functions with side effects can't be tested with simple unit tests;
that has nothing to do with autonomous transactions.
