"func" The function
"dict" The dictionary
"args" The list with arguments
"name" The function name
"func" The function
"dict" The dictionary
"args" The list with arguments
"arity" A dictionary with information about the number of
arguments accepted by the function (minus the
{arglist}) with the following fields:
required the number of positional arguments
optional the number of optional arguments,
in addition to the required ones
varargs |TRUE| if the function accepts a
variable number of arguments |...|
Note: There is no error, if the {arglist} of
the Funcref contains more arguments than the
Funcref expects, it's not validated.
Returns zero on error.
