The first, by a factor of about 5 when line[1] is not '[', and by a
factor of about 3 when it is, the difference being whether the "and"
part is short-circuited.
The second is always much slower because it has to create and destroy
a sequence of length 2.

There is a builtin time() function which you can use to test this )
