                   Keyword

Known Subclasses:: CaselessKeyword

Token to exactly match a specified string as a keyword, that is, it must be immediately followed by a non-keyword character. Compare with Literal:

 Literal("if") will match the leading 'if' in 'ifAndOnlyIf'.
 Keyword("if") will not; it will only match the leading 'if in 'if x=1', or 'if(y==2)'

Accepts two optional constructor arguments in addition to the keyword string: identChars is a string of characters that would be valid identifier characters, defaulting to all alphanumerics + "_" and "$"; caseless allows case-insensitive matching, default is False.
