R devel - Sep 2020 - inaccurate description of 'init' argument in ?Reduce

Hello list,

In ?Reduce:

   init: an R object of the same kind as the elements of ?x?.

Seems like "the same kind" is an unnecessary and artificial
restriction.
Furthermore, there is no notion of "same kind" for heterogeneous
lists:

   x <-  list(letters, c(TRUE, FALSE))

   Reduce(function(init, xx) {init + length(xx)}, x, init=100)
   # [1] 128

Thanks,
H.
