12# In the following conditions, ${SIDE_EFFECT} is the position of the first
13# parse error.  Before cond.c 1.286 from 2021-12-10, it was always fully
14# evaluated, even if it was not necessary to expand the variable expression.
15# These syntax errors are an edge case that does not occur during normal
16# operation.  Still, it is easy to avoid evaluating these expressions, just in
17# case they have side effects.
