Hi Stas, thanks for hooking into this thread
However, committing to having specific object ID (e.g. as integer) as > part of public API is pretty big commitment This is already part of the public API: var_dump and debug_zval_dump do expose object IDs to userland. It's just inefficient to get for more advanced use cases. Even if its internal implementation is totally different from PHP's, HHVM adds an id to every object, just for this requirement: matching what PHP exposes to userland. I'd more than happy to have an spl_object_id() function btw! Nicolas
