Greetings,
I noticed that starting with R version 3.5.0, it is now possible to do,
for example:
setGeneric(name = "foo",
def = function(x, y, ...) standardGeneric("foo"),
valueClass = "fooResult"
)
setMethod(f = "foo",
Not certain this is actually a bug, so posting here.
I'm on Ubuntu 18.04.4 LTS, building R version 4.0.0. The "configure" and
"make" steps are successful, but the "make check" step fails when it
gets to this part of ./tests/reg-tests-1b.R:

Hi,
I'm aware that the language definition states R objects are often

I realize that

You could write convenience functions, but I have used the C99 mechanism
