Viability on non-Apple platforms

Naturally this only works on platforms where Swift is backed by an Objective-C runtime. I wonder how we could extend this to other platforms where this isn‘t available, perhaps using a global in memory storage area?

Indeed, due to the dependency on ObjectiveC, the build was failing on Linux.

The basic implementation by Apple of associatedObject is found in the following.

https://github.com/apple-oss-distributions/objc4/blob/689525d556eb3dee1ffb700423bccf5ecc501dbf/runtime/objc-references.mm

A similar implementation might allow for similar functionality outside of the Apple platform.

Hello, @mickeyl It's been some time, but I just created a library of Associated object that can work on Linux and other platforms.

I would like to consider including its introduction to this AssociatedObject Macro in the future.
