 We let .value() for continued fractions return a real lazy field element
 when there is no other possibilities. For example
 {{{
 sage: cf = continued_fraction(words.ThueMorseWord([1,2]))
 sage: cf
 [1; 2, 2, 1, 2, 1, 1, 2, 2, 1, 1, 2, 1, 2, 2, 1, 2, 1, 1, 2...]
 sage: v = cf.value()
 sage: v
 1.422388736882786?
 sage: v.parent()
 Real Lazy Field
 sage: v.n(digits=30)
 1.42238873688278548834154711602
 }}}
