My new language is great, but it has a few quirks regarding type:
[[Gray and white type on a black background.]]
 [1]> 2 + "2"
  =>  "4"
 [2]> "2" + [ ]
  =>  "[2]}
 [3]   (2
0)
  =>  NaN
 [4]> (2
0)+2
  =>  NaP
 [5]> ""+""
  =>  '"+"'
 [6]> [1,2,3] + 2
  =>  FALSE
 [7]> [1,2,3] +4
  =>  TRUE
 [8] 2
(2-(3
2 + 1
2))
  =>  NaN.00000000000000013
 [9]> RANGE(" ")
  =>  (' " ',  "!", "  ", '"')
[10]> +2
  =>  12
[11]> 2+2
   => DONE
[14]> RANGE (1,5)
   =>  (1,4,3,4,5)
[13]> FLOOR(10.5)
   =>  |
   =>  |
   =>  |
   =>  |___10.5___ 

{{Title text: colors.rgb("blue") yields "#0000FF". colors.rgb("yellowish blue") yields NaN. colors.sort() yields "rainbow"}}
