Investigate the `getSymbol` function in the String module

[aspeddro]

The String module has three functions for interacting with Symbols.

1. getSymbol
2. getSymbolUnsafe
3. setSymbol

• Are these bindings necessary?
• Should we move to another module?

Is there any example case for these bindings?

String.getSymbol("name", Symbol.make("name"))

Compile to:

"name"[Symbol("name")]

These are also in Array. I touched on it briefly in #51, suggesting that they should be named getBySymbol and setBySymbol instead. But good to question their usefulness first.

Oh I see you already raised this issue. I agree the naming is confusing and should be getBySymbol everywhere.
