# In the following conditions, ${SIDE_EFFECT} is the position of the first
# parse error.  Before cond.c 1.286 from 2021-12-10, it was always fully

# These syntax errors are an edge case that does not occur during normal
# operation.  Still, it is easy to avoid evaluating these expressions, just in
# case they have side effects.
