Comment (by craigcitro):
I definitely prefer the v2 patch for the sake of readability. For the sake
of it, though, should anyone look at this ticket, I want to note that the
original patch seems (at a quick glance, anyway) to be faster:
{{{
sage: s = ""
sage: %timeit s.startswith('3')
1000000 loops, best of 3: 350 ns per loop
sage: %timeit s and s[0] == '3'
10000000 loops, best of 3: 72.2 ns per loop
sage: s = "345"
sage: %timeit s.startswith('3')
1000000 loops, best of 3: 353 ns per loop
sage: %timeit s and s[0] == '3'
1000000 loops, best of 3: 208 ns per loop
sage: s = "678"
sage: %timeit s.startswith('3')
1000000 loops, best of 3: 351 ns per loop
sage: %timeit s and s[0] == '3'
1000000 loops, best of 3: 212 ns per loop
}}}
