I presume you are asking: Why hasn't slice been converted from a
'mere' function to a callable type like int, str, and float have been?

If this has not yet been done for the coming 2.3, I presume it will be
as soon as someone capable of doing the conversion decides to do so.
Slice was originally added for use by Numerical Extensions and so far
has probably seen little use by anyone else.  Hence its conversion is
of lesser priority.
