Do you count the fact that a loop starts two scopes, not one?
for (my $x = 0; $x < 10; ++$x) {
# stuff
my $y = $x;
# more stuff
}
Note that $x and $y are in different scopes. $y is local
to the body of the loop. $x is global to the loop.
Also for some definition of scope, <package> starts a new
scope.
And if we want the source differing, an if starts a scope
and is different from either a block or a loop - try to
do redo and it ignores the enclosing if for the
enclosing block or loop.
I have also had occasion to run Perl code in a different
process by opening a pipe to it, writing my code on the
pipe, and then sending __END__. Does that count?
What about running code using reval from Safe? Does
that count as different from eval?
