Booleans - language feature

< >
Example from Go:
c := true
const result = true
Example from Nim:
let res = true
Example from Ion:
null.bool true false
Example from Slope:
(define open? #t)
Example from Jule:
true false
Example from Bel:
; The symbol nil represents falsity as well as the empty list. ; The symbol t is the default representation for truth, but any object other than nil also counts as true.
Example from opengraph:
true false 1 0
