Actually, the
if being evaluated first is
exactly what we would want in any case. You are missing the
implication of the behavior, however. The variable, besides
being localized which is unexpected (until one realizes that
data scoping is done at compile-time in this case), also
becomes static; that is, it retains its value between calls,
which is unexpected behavior for a local via
my
variable. See
iakobski's reply in this thread
for more details.
