Overview of Dict, Variant and Optional in Mojo🔥

[@aethermass]

Is a String ever not a StringKey? Seems like the base String class should just implement the interface for StringKey. The current implementation seems to handle this with a conversion. Does that have a performance impact opposed to making the base String class implement the methods from StringKey?

@aethermass this seems already implemented for String / StringLiteral -> Implemented traits: AnyType, Boolable, CollectionElement, Copyable, EqualityComparable, Hashable, IntableRaising, KeyElement, Movable, Sized, Stringable

No dict copy?

Glad to see more features being added, keep up the amazing work

Dict is very very slow. Way much slower than in python!
