This function:

enables a program to instantiate any class defined in the
program. To make it work, though, every class in the program
has to have a TypeInfo generated for it. This leads to bloat:

and sometimes the bloat can be overwhelming.
The solution seems straightforward - only have Object.factory
be able to instantiate classes marked as 'export'. This only
makes sense anyway.
What do you think?
An alternative which would be more work but wouldn't break code
would be to put the "all the classes" structure in a separate
section, which is only referenced by Object.factory. Thus, the
structure will be GC-ed by the linker, unless Object.factory is
actually used somewhere in the program.
Not sure how this would tie in with shared objects though. Maybe
this needs to be combined with your "export" idea.
