That brings me to another point which will make you guys think i'm
crazy and close this thread immediately :-). I actually tried that
recently (that being using a float as an index), actually used it as a
slice. I would think that should work, it should round the float
usually, and if used in a slice, if it is an end it should round up,
if it is a start round down, for 0.5?

Maybe I should write my first PEP and watch it thrown out :-)
