Not exactly true. The scope is from the definition to the closing
brace. Not the whole block. Try this
$perl
use strict;
{
print "$x";
my $x = 5;
print "$x";
}
Plus there are a special "syntactic sugars" :
for (my $i = 0; $i < 10; $i++) {
...
}
where the scope is the code in the round braces plus the inner
block. See :
use strict;
{
for (my $i = 0; $i < 10; $i++) {
print "$i\n";
}
print "Outside: $i\n"
}
Similar for "foreach my $var (@array) {...}" and
"while (my $i = <HANDLE>) {...}".

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain.
I can't find it.
