Huh, this will affect all Nan-boxing vm's, like v8, luajit, etc. Didn't know that they even had this 5level config already. 9 bits less for additional types now

Huh, this will affect all Nan-boxing vm's, like v8, luajit, etc. Didn't know that they even had this 5level config already. 9 bits less for additional types now. But in reality you would be fine even with the last 3 bits, as in most not-nan boxing fast vm's.
