Hi internals,
I've tracked down a memory leak to an anonymous class created within eval():
```
for ($i = 0; $i < 1000000; $i++) {
$object = eval('return new class {};');
if ($i % 1000 == 0) {
echo memory_get_usage() . "\n";
}
}
```
The memory usage quickly ramps up and memory_limit is reached in seconds.
Without eval(), the memory usage stays flat. I'm on 7.3.6.
*Is this a bug?* Or is this some inherent limitation of eval() that cannot
be fixed?
Thanks for any insight.

*In case you're wondering (I'm sure you are!), I need this to dynamically
create an object that implements an arbitrary number of interfaces
