(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.Returns the new tuple.
(tuple/sourcemap tup) Returns the sourcemap metadata attached to a tuple, which is another tuple (line, column).
