That's true. So perhaps there should be a flag that turns on this error
checking. Often "args" is just a list that gets generated automatically and you
don't know what all of its elements are. It just leads to a bit of
non-deterministic behavior. It would be useful to have the option of flagging

Sure, it would have helped you figure out your issue, but you don't
want a *warning* when you pu
Thanks for the explanations.
Wouldn't the following bit of checking in do.call() make it easier to figure
such things out in the future?
my.call <- function(what,args,...) {
## Get the name of the function to call.
if (!is.character(what))
whatStr <- deparse(substitute(what))

Because 'all' is the name of one of the arguments to cbind.zoo:
R> args(cbind.zoo)
function (..., all = TRUE, fill = NA, suffixes = NULL, drop = FALSE)
NULL
do.call constructs a call somewhat like:
R> cbind(test=zz$test, all=zz$all, foo=zz$foo)
The same thing would happen for list elements named
