-			# A WordList is a Hash with some additional features.
-			# It is intended to be used for keyword recognition.
-			#
-			# WordList is highly optimized to be used in Scanners,
-			# typically to decide whether a given ident is a keyword.
-			#
-			# Example:
-			# 
-			#  # define word arrays
-			#  RESERVED_WORDS = %w[
-			#    asm break case continue default do else
-			#    ...		
-			#  ]
-			#  
-			#  PREDEFINED_TYPES = %w[
-			#    int long short char void
-			#    ...
-			#  ]
-			#  
-			#  PREDEFINED_CONSTANTS = %w[
-			#    EOF NULL ...
-			#  ]
-			#  
-			#  # make a WordList
-			#  IDENT_KIND = Scanner::WordList.new(:ident).
-			#    add(RESERVED_WORDS, :reserved).
-			#    add(PREDEFINED_TYPES, :pre_type).
-			#    add(PREDEFINED_CONSTANTS, :pre_constant)
-			#
-			#  ...
-			#
-			#  def scan_tokens tokens, options
-			#    ...
-			#    
-			#    elsif match = scan(/ [A-Za-z_][A-Za-z_0-9]* /x)
-			#      # use it
-			#      kind = IDENT_KIND[match]
-			#      ...
