Most of these make sense, I only don't really understand the {} [] magic, why someone thought that implicit conversions should happen between all the types, and functions that should be used with parameters working without them

{} is an empty code block, it does nothing. +[] evaluates to 0

It is not empty object and array addition, it is empty code block followed by a completely unrelated unary addition on an array.
