This function:
http://dlang.org/phobos/object.html#.Object.factory
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:
https://issues.dlang.org/show_bug.cgi?id=14758
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?
Can't this be optional?
-slim-rtti // hold the gravy
-verbose-rtti // more gravy!

The principle often used by languages (C, C++, Rust) is you
only pay for what you use. With Object.factory, every program
pays for it with every class, despite very few actual uses of
it.
Object.factory() would probably get more use if D provided a full
solution in this category.
OffsetTypeInfo was never implemented, but is still collecting
dust:
https://github.com/D-Programming-Language/druntime/blob/master/src/object.d#L197
I would love to see OffsetTypeInfo implemented, and have the
field name included as well so it could be used for serialization.
I don't believe there has to be a "one size fits all" solution
for this. Some people need small binaries, some need utility.
