basic list display

Code
  x <- 1:10
  y <- list(x, x)
  ref(x, list(), list(x, x, x), list(a = x, b = x), letters)
Output
  [1:0x001] <int>

  █ [2:0x002] <list>

  █ [3:0x003] <list> 
  ├─[1:0x001] 
  ├─[1:0x001] 
  └─[1:0x001]

  █ [4:0x004] <named list> 
  ├─a = [1:0x001] 
  └─b = [1:0x001]

  [5:0x005] <chr>

basic environment display

Code
  e <- env(a = 1:10)
  e$b <- e$a
  e$c <- e
  ref(e)
Output
  █ [1:0x001] <env> 
  ├─a = [2:0x002] <int> 
  ├─b = [2:0x002] 
  └─c = [1:0x001]

environment shows objects beginning with .

Code
  e <- env(. = 1:10)
  ref(e)
Output
  █ [1:0x001] <env> 
  └─. = [2:0x002] <int>

can display ref to global string pool on request

Code
  ref(c("string", "string", "new string"), character = TRUE)
Output
  █ [1:0x001] <chr> 
  ├─[2:0x002] <string: "string"> 
  ├─[2:0x002] 
  └─[3:0x003] <string: "new string">
