in thread Difference between $1 and \1.

$str = aa;

Unless you have a variable named aa somewhere, that line will give you an error.

It is only an error when strict subs are in effect. 
{
    no strict 'subs';
    my $str = aa;

    say $str;
}

Though having strict on is almost always a good thing.
