c, cbind and rbind more consistent to base R #252
Description
It would be nice to have c.integer64, cbind.integer64, and rbind.integer64 more consistent with base R.
c(A=as.integer64(1L), B=list(aa=1, bb=2:1))
# Error in UseMethod("as.integer64") :
# no applicable method for 'as.integer64' applied to an object of class "list"
vs.
c(A=1L, B=list(aa=1, bb=2:1))
# $A
# [1] 1
#
# $B.aa
# [1] 1
#
# $B.bb
# [1] 2 1
or
cbind(A=as.integer64(1L), B=matrix(1:6, 2))
# integer64
# A B
# [1,] 1 1
# [2,] 1 2
# [3,] 1 3
# [4,] 1 4
vs.
(A=1L, B=matrix(1:4, 2))
# A
# [1,] 1 1 3
# [2,] 1 2 4
