-In each case, some values are used as inputs to functions while others are the functions being applied. The result of a function can be used either as an input or as a function again. These expressions correspond to the APL expression where `a` and `e` are arrays, `b` and `c` are functions, and `d` is a monadic operator. However, these syntactic classes have to be known to see what the APL expression is doing—they are a form of context that is required for a reader to know the grammatical structure of the expression. In a context-free grammar like that of simple C or Lisp expressions, a value's grammatical role is part of the expression itself, indicated with parentheses: they come after the function in C and before it in Lisp. Of course, a consequence of using parentheses in this way is having a lot of parentheses. BQN uses a different method to annotate grammatical role:
