aren't they implied strings? If "[a b c]" is an array of 3 strings, "a", "b" and "c", then True is a string "True". That's the problem.
"Strings can also be delimited with a single quote character which allows for a string to be either "abc" or 'abc'."
There's no mention of having a string without a delimeter.
