cfunction
(tuple/slice arrtup [,start=0 [,end=(length arrtup)]])
Take a sub sequence of an array or tuple from index start inclusive to
index end exclusive. If start or end are not provided, they default to
0 and the length of arrtup respectively. 'start' and 'end' can also be
negative to indicate indexing from the end of the input. Note that
index -1 is synonymous with index '(length arrtup)' to allow a full
negative slice range. Returns the new tuple.
