Enum boa::builtins::function::ThisMode

pub enum ThisMode {
    Lexical,
    NonLexical,
}

Defines how this references are interpreted within the formal parameters and code body of the function.

Arrow functions don't define a this and thus are lexical, functions do define a this and thus are NonLexical
