Now, THIS I like!
There's now a "mock-up" of this in git.
A question remains: what becomes of the optional third argument to
lags()? In the series (or list) version, that option lets you
arrange the output "by lag" rather than "by variable", while in
mlag() the extra argument lets you specify a value other than zero
for the missing elements. What should it do in the matrix-arg
variant of lags?
