the help page says:
'is.list' returns 'TRUE' iff its argument is a 'list' _or_ a
'pairlist' of 'length' > 0, whereas 'is.pairlist' only returns
'TRUE' in the latter case.
does the "latter case" mean a 'pairlist' of 'length' > 0?
but
> is.pairlist(pairlist())
[1] TRUE
> length(pairlist())
[1] 0
what the help page exactly means?
