'set' resource doesn't handle type mismatch

[czerwinskilukasz1]

When trying to use set on an object, it fails with an Uncaught TypeError: arr.slice is not a function. We should add type validation and our own error handling.

🦄 .editor
// Entering editor mode (^D to finish, ^C to cancel)
let a = {}
a:set('a', 'value')

Uncaught TypeError: arr.slice is not a function

a:set('a', 'value') is set(a, 'a', 'value') is set({}, 'a', 'value') is {} = 'a' so no wonder this throws. Error message should be more informative though
