TypeInfo is generated at declaration time. At that point you
can't even know if a struct will be allocated on the heap at
some point.
I was wondering... Would it be possible to make selective
TypeInfo ?
-Eg. Only add TypeInfo for those things that really need it.
If that's possible, then I think the overhead could be decreased
dramatically.
Another way it could perhaps be reduced, would be to change
strings into pointers or identifiers. This popped into my mind,
because it appears that TypeInfo is zero-terminated C-strings
anyway. If those exist in a read-only memory space, then
comparing them using strcmp seems quite extraneous; just compare
the pointer and put some other data there instead; or make a
32-bit uniqueID (perhaps even a 16-bit UID).
