Is there any specific case where you can't treat
{
my $foo = 12;
print $foo;
my $foo = "ho";
print $foo;
}
as
{
my $foo = 12;
print $foo;
{
my $foo = "ho";
print $foo;
}
}
(where my outer {}s may just be the scope represented by the beginning and end
of the file)
ie implicitly start a new block just before any duplicate my, which continues
until the point the current block ends.
