@Duncan, @Jeff: thanks for giving me your opinions, I really appreciate
that! I'm not saying that this is something that should *generally* be used
and I perfectly understand your concerns. However: correct me if I'm wrong,
but actually I'm not doing much more than generalizing the idea behind

You have some interesting ideas about what makes for improvements in parameter
interfaces. Wrapping the arguments into a list is like creating an object to
represent all of them, except that you don't have the benefits of a class to go
with that cognitive shift. And if making classes to hold par

Thanks for the info/suggestions!
But note that it's not just a one-step, but a two step dispatching process
with respect to `...`. That is, `foo()` and `bar()` are *not* both called
directly inside `foobar()`: `foobar()` only calls `foo()` which then calls
`bar()`.
I now came up with something al

AFAIK You have to alter the name of at least one of the y arguments as used by
foobar, and anyone calling foobar has to read about that in the help file. That
is only one y can be in "...". e.g.
foobar <- function( x, y_foo, ... ) {
foo( x, y=y_foo, ... )
bar( x, ... )
}

Dear list,
I wonder if there's a clever way to fine control the exact way arguments
are dispatched via R's "three dots" argument
Consider the following use case:
- you have a function foobar() that calls foo() which in turn calls bar()
- *both* foo() and bar() have an argument that's
7 matches
