The patch allows to prepend a (finite) list to a (potentially infinite)
infinite list:
{{{
sage: from sage.misc.lazy_list import lazy_list
sage: from itertools import count
sage: l = lazy_list(i**2 for i in count()); l
lazy list [0, 1, 4, ...]
sage: ['toto', 'bibi'] + l
lazy list ['toto', 'bibi', 0, ...]
}}}
