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