The \var{function} argument must be a callable object (a user-defined or
built-in function or method, or a class object) and the \var{args}
-argument must be a tuple. The \var{function} is called with
-\var{args} as argument list; the number of arguments is the the length
+argument must be a sequence (if it is not a tuple, the sequence is
+first converted to a tuple). The \var{function} is called with
+\var{args} as the argument list; the number of arguments is the the length
of the tuple. (This is different from just calling
\code{\var{func}(\var{args})}, since in that case there is always
exactly one argument.)
