No, that's perfectly legal in perl5; it just generates a warning:
use warnings;
my $x = 1;
my $f1 = sub { $x };
my $x = 2;
my $f2 = sub { $x };
printf "f1=%d f2=%d x=%d\n", $f1->(), $f2->(), $x;
which gives
$ perl588 /tmp/p
"my" variable $x masks earlier declaration in same scope at /tmp/p line 6.
f1=1 f2=2 x=2
