/w isn't the pattern for matching the first character in identifiers. I never consider \w when matching that first character. In unicode, the pattern to follow is likely /\A\p{IdFirst}\w*\z/. In ASCII, the pattern is /\A[[:alpha:]_]\w*\z/. The pattern /\^\w+\z/ is always wrong when matching identifiers.
