There is a trace macro but it doesn't provide complete traces without explicitly adding every function you want to trace, which becomes tricky very soon. Manual tracing with printf()s like in non-functional languages isn't built-in either. There are half-baked macros for this on blogs if you google hard enough, but that is not the kind of thing that leaves a solid impression of a language.
Maybe I was just working in a non-clojuresque way.
For me, however, its not a reason to quit.
