Jeremie Pelletier: >I usually test for the string length before slicing it.<
Me too, but: - mammals aren't perfect, and sometimes they forget things, etc. A compiler, once well programmed, will not forget such tests. - such tests added by me and you slow down code a little (but a good compiler can remove some of them, GCC and LLVM are able to). This may mean that the time saved by D slices being non-saturating (unlike Python ones) may be spent anyway by tests added manually by the programmer. If this is true (and I think it may be true, I'd like to instrument LDC to run a slicing-heavy D program with and without saturation in slice bounds to test if I am right here) then the saturating nature of Python slices is better under all points of view, nearly efficiency-neutral too :-) Bye, bearophile
