Weakmap Polyfill Laravel Package

✨ New features

• WeakMap now performs housekeeping on GC cycle collection (automatic and via gc_collect_cycles()) by @mvorisek (#10)
• WeakMap is now properly annotated with [@template](https://github.com/template) (for static analysis)

🩹 Compatibility improvements

• Fixed Error type / message when passing null instead of object in isset() / unset()

🐛 Bug fix

• Fixed behaviour of isset() with null value by @mabar (#7)

🚀 Performance improvement

• housekeeping is now performed less often for large WeakMaps (#4)

💥 Compatibility improvement / breaking change

• serializing & setting dynamic properties is now forbidden, like native WeakMap (#6)

Thanks to @TysonAndre!

WeakMap now throws:

• TypeError when using a non-object as a key
• Error when appending ([]) to a WeakMap

In accordance with the specs.

Thanks to @BackEndTea!
