# janet 1.10.1

# non-numeric values appear to always be greater than numeric values
( $<$  math/inf nil)      # -> true
( $<$  math/inf true)     # -> true
( $<$  math/inf false)    # -> true
( $<$  math/inf "hello")  # -> true
( $<$  math/inf :heyo)    # -> true
( $<$  math/inf (fn []))  # -> true
( $<$  math/inf {:a 1})   # -> true

# non-numeric values also follow an ordering.
# rearranging any of these values turns the result false:
( $<$  nil false true "a" "b" :a :b [] [1] [1 1] [2] {} {:a 1} (fn []))  # -> true
