Tacit #5
The Array Cast
Function Operators and Syntax Confusion
This chapter discusses the function or return operator in BQN and its syntactic role. It also addresses the confusion surrounding monadic and dyadic forks and the lack of vocabulary to discuss the arity of functions and arguments. The discussion touches on explicit and tacit code and the multiple meanings associated with certain function names. The chapter ends with a mention of ambivalence and Adam being given the opportunity to speak.
