(tuple/brackets & xs) Creates a new bracketed tuple containing the elements xs.
(tuple/setmap tup line column) Set the sourcemap metadata on a tuple. line and column indicate should be integers.
(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.
(tuple/sourcemap tup) Returns the sourcemap metadata attached to a tuple, which is another tuple (line, column).
(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.
