I don't see any straightforward way to write a function that, when executed inside a debug REPL, quits the REPL. The only way to get out of a REPL is to have the its reader function return an object created specifically for this purpose (and passed to the reader function). Therefore any straightfoward method for quitting the REPL must be based on objects returned by the reader, before evaluation. It is probably possible to get around this by having a function that modifies a global var which in turn is read by the REPL to decide when to quit, but that's not what I'd call straightforward. What *is* doable easily is quit whenever the reader sees the form (debug-repl-quit). But it's the literal form and not its value. I guess that would be good enough for the typical usage scenarios of a debug REPL, but still it's not really a function call. Perhaps a keyword would be a better choice to mark the difference.
