Icon does--you would write

	if (10 < kick_back < 100) . . .

Reason:  The "<" operator in Icon is left-associative and returns its right
operand.  Success/failure of an expression is a separate concept from
result value.  Incidentally, if the first comparison (the "10 < ..." part)
fails, the second part ("... < 100") is not performed.

(Icon deserves serious study by language designers, etc.)
