Yes, you are right about the lexical binding; I suspect that is less likely to hit people though. I don't know why I keep typing (instance? String) but I've done it a lot. Possibly because I am using a Java API with a lot of very similar classes; by the time I have managed to find out which cla

Sometimes people separate a macro into the macro itself, and a normal function that does the actual work. The normal function often has the same name as the macro but with a * suffix. Chris On 28 February 2013 13:38, Dave Sann wrote: > I see cases of * after function names. > > Can anyone enli

Just a general pointer: the bytecode verification that the JVM performs when loading a class has failed. There is a code path through the bytecode of the mentioned method such that it pops more than it pushes (Java bytecode is a stack-oriented machine language). So it makes sense that it blows

Nondeterministic behavior -> suspect race conditions. Maybe compilation was happening concurrently on several threads and the resulting bytecode got mangled. On Thursday, February 28, 2013 4:17:52 PM UTC+1, Jim foo.bar wrote: > > On 28/02/13 15:12, Alex Robbins wrote: > > Maybe you are already

I don't have the regular compile-and-load route in mind; this doesn't use concurrency. However if the runtime evaluation of a form results in just-in-time bytecode generation and classloading, I don't see why this couldn't be happening in any thread. Whether any of this could actually result in
