Asserts that the type of a given SassScript value is the expected type (designated by a symbol).
Valid types are ‘:Bool`, `:Color`, `:Number`, and `:String`. Note that `:String` will match both double-quoted strings and unquoted identifiers.
@example
assert_type value, :String assert_type value, :Number
@param value [Sass::Script::Literal] A SassScript value @param type [Symbol] The name of the type the value is expected to be @param name [String, Symbol, nil] The name of the argument.
