The following information may be useful.

lobject.h, in the comments starting at line 31, gives information on
how the type tag is used. Bits 0--3 encode the main type, bits 4-5
the subtype, bit 6 whether the object is collectable. One can deduce
that in the present implementation, starting at bit 7, the rest of the type
tag is currently unused.
