• != (opdef):  – alias of not-eq
• < (opdef):  – Check if values are in ascending order.
• <= (opdef):  – Check if values are in ascending order.
• == (opdef):  – alias of eq

details

• < (opdef):  – Check if values are in ascending order.

  (< a b [c…]) (asc? a b [c…])

• <= (opdef):  – Check if values are in ascending order.

  (<= a b [c…])

• > (opdef):  – Check if values are in descending order.

  (> a b [c…]) (desc? a b [c…])

• >= (opdef):  – Check if values are in descending order.

  (>= a b [c…])

• and (opdef):  – Logical AND.

  (and a b [c…])

• bool (opdef):  – Cast value to bool.

  (bool a)

  false if a is false, nil or 0, true otherwise.

• eq (opdef):  – Check for equality.

  (== a b [c]…) (eq a b [c]…)

  true if the types and values of all arguments are equal.

• not (opdef):  – Logical NOT.

  (not a)

• not-eq (opdef):  – Check for inequality.

  (!= a b [c]…) (not-eq a b [c]…)

  true if types or values of any two arguments are different.

• or (opdef):  – Logical OR.

  (or a b [c…])
