Perhaps it is, but I've not understood why, could you explain? As I see it,
if we have the following code now:
$x = 2;
{
$x = 1;
}
print "$x\n";
we will get the following output:
1
But if lexicals were the default, then the same code would print
2
because it would be equivalent to todays:
my $x = 2;
{
my $x = 1;
}
print "$x\n";
Would it not?
