/**
 * The entire purpose of this function is for use to debug values inline
 * without changing the flow of the code too much.
 *
 * This **MUST** be a non-arrow function to allow access to the `arguments`
 * object.
 *
 * This function expects at least one argument.
 *
 * If more than one argument is provided, then:
 * a) the last argument is considered the value, and will be returned
 * b) all other arguments will be converted to string and output
 *
 * If only one argument is provided, it is considered the value, and will be
 * returned.
 *
 * Zero arguments is an error condition.
