What if your substrings have parentheses in them? How do you know, when you
come to a parenthesis, whether it terminates your substring, or is a
character within your substring?

Example:
myString = '1(a)2(b)3'

That could be either "1(substring)3"
where substring is "a)2(b"

Or it could be "123"
with two substrings of "a" and "b"

How do you know which it supposed to be?
