    if you try

    $$a = 'hello world';
echo $$a; //displays hello world
echo $$aa; //displays hello world
echo $$aaa; //displays hello world


die( "<pre>" . print_r( get_defined_vars(), true ) . "</pre>" );

    You can see that it has registed a variable with no name so yes, according to PHP’s naming conventions, this would be a bug
