We all know that if you google the word "google" it will break the internet.

Your task is to create a function that accepts 1 string and returns its length, in as few amount of Unicode characters as possible.

However, if the given string is google (lowercase), it will cause an error.

For example, g('bing') will return 4 but g('google') will cause an error.

Please provide an example of usage, and the error if possible.
