Returns a new StringScanner object whose stored string is the given string; sets the fixed-anchor property:
Example
scanner = StringScanner.new('foobarbaz') scanner.string # => "foobarbaz" scanner.fixed_anchor? # => false put_situation(scanner) # Situation: # pos: 0 # charpos: 0 # rest: "foobarbaz" # rest_size: 9
