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

Your task is to create a function that accepts one string and returns its length, in the fewest possible Unicode characters.

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.
