2010-07-06byte_slice: String#[range] is faster than String#slice!(range)
rb_str_slice_bang() allocates a new string internally and calls rb_str_aref_m() AND rb_str_aset_m(), too. String#[] just calls rb_str_aref_m() directly, so it's a much quicker code path. Also, "[]" methods dispatch faster under 1.9, too.
