For what it's worth I think the increased emphasis on classed
errors should help with this (i.e., it will be easier to filter out
errors you know are false positives/irrelevant for your use case).

Let me expand a bit, I might have expressed myself poorly.
If there is a good reason for a warning I want a warning, and because I
take them seriously I don't want my console cluttered with those that can
be avoided. I strongly believe we should strive to make our code silent,
and I like my

Thanks and good point about unspecified behavior. The way it behaves now
(when it doesn't ignore) is more consistent with data.frame() though so I
prefer that to a "warn and ignore" behaviour:
data.frame(a = 1, b = 2, 3)
#> a b X3
#> 1 1 2 3
data.frame(a = 1, 2, 3)
#> a X2 X3
#> 1 1 2
Note that ?transform.data.frame says arguments need to be named, so you
are testing unspecified behaviour. I guess this falls in a similar
category as the note
If some of the values are not vectors of the appropriate length,
you deserve whatever you get!
