(tuple/brackets & xs) Creates a new bracketed tuple containing the elements xs.
(tuple/setmap tup start end) Set the sourcemap metadata on a tuple. start and end should be integers representing byte offsets into the file. Returns tup.
(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. The mapping is represented by a pair of byte offsets into the the source code representing the start and end byte indices where the tuple is.
(tuple/type tup) Checks how the tuple was constructed. Will return the keyword :brackets if the tuple was parsed with brackets, and :parens otherwise. The two types of tuples will behave the same most of the time, but will print differently and be treated differently by the compiler.
