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?

If you ask mathematicians what they do, yo always get the same answer. They
think. They think about difficult and unusual problems. They do not think
about ordinary problems: they just write down the answers.
