In a situation where you want to understand values flowing through some point in your system, you might use println or logging to understand what is flowing.
What are the problems with println/logging? - both: about strings, not values - both: hard-wires the putting of the value to where the value goes (log f/ws have some flexibility there) - logging: requires you to add logging crap to your requires and deps - println: hard-wires where things go to a stream that's difficult to rebind in a global way tap is a means to convey values (not strings) via a queue (see: Language of the System) where you can dynamically choose to attach and detach handler(s) to tell it to put values wherever you want (a log, a metric, println) - but those are decoupled from where you convey the values. tap> is in core so it's as easy to add to your code as println.
