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.
