Possibly. Since I program to interfaces, every reference I use is 
referenced to an interface. Needing the correct object size for 
implementing an allocator was not working as "expected"(at least 
as one would expect with classes). I could not see anything in 
the docs that would suggest otherwise(else the light bulb might 
have went off).

i.e., one would expect, IMO, that tsize would work on interfaces 
because interfaces do not have a "size" so it should return the 
class size of the object. (so things work uniformly and we can 
program to interfaces without having to create workarounds).
