| require_float_parameter | Given a Value assumed to be a Value::List(), grab the item at index,
assumed to be a Value::Float(), and return its inner f32. Err if any part
of this fails.
|
| require_int_parameter | Given a Value assumed to be a Value::List(), grab the item at index,
assumed to be a Value::Int(), and return its inner i32. Err if any part
of this fails.
|
| require_list_parameter | Given a Value assumed to be a Value::List(), grab the item at index,
assumed to be a Value::List() or a Value::Nil, erring if that isn't
the case.
|
| require_parameter | Given a Value assumed to be a Value::List(), grab the item at index
and err if there isn't one.
|
| require_string_parameter | Given a Value assumed to be a Value::List(), grab the item at index,
assumed to be a Value::String(), and return a reference to its inner
String. Err if any part of this fails.

| vec_refs_to_cons | Same as vec_to_cons() but takes a &Vec<&Value> instead.
|
| vec_to_cons | Convert a &Vec to a cons list (Value::List()) containing the
sequence of values from the Vec.
