Yeah, that would be helpful for when you need to use a more compositive
approach and when you want an object to take on multiple roles (e.g. some
sort of mediator or controller). Currently you need to create subclasses
for every role but those classes are only use once with the mediator for a

The biggest problem you may have with this is requesting a post 2.1 context
in Mac OS X since Apple decided to create a schism in versioning and only
supports either 2.1 and below or 3.2 core and above. They do not have
ARB_compatibility.
Same with Mesa, meaning that on Linux you can use either 2.
Yes this is what i meant. I'd expect that the sizeof(pointer) to return the
target architecture's pointer size, not the architecture of the compiler's
own executable.

So wait, the following code:

But there are tons of left-sided keywords, like specialize, const, pointer,
array, file, var, out, etc. And as i said, "weak Foo" reads better than
"Foo weak"
Looks good, this will certainly help simplify some of my code :-).
My only comment will be about the placement of "weak"... wouldn't make more
sense to put it in front of the type (ie "weak TTest" instead of "TTest
weak"), similar to how other stuff like const, var, specialize, etc work?

Lazarus has a Pascal tokenizer unit under components\mpaslex\mpaslex.pp. It
seems old and doesn't look like it supports the full FPC syntax, but it
might be a starting point since most likely you can convert the code to C++

It depends on the compiler mode, not the platform - at least according
to the docs in http://www.freepascal.org/docs-html/ref/refsu5.html:

The integer type maps to the smallint type in the default Free Pascal
