This function and class creates a template Function object which we can use to build a native, compiled function.
This is not to be confused with the R reserved
word function.
Function(name, retType, paramTypes = list(), module = Module(), varArgs = FALSE, ...)a string giving the name of the function
the return type of the new function. This should be of
class Type-class.
a list giving the types of the parameters of the function. These can be named or not.
the module in which the function is to be defined
a logical value that indicates whether the routine has variadic arguments, i.e. passed to it via … (not the … in this function)
additional inputs for this call (not for calling the routine)
An object of class Function
