You can do something like this (PLT Scheme):

That doesn't seem like a good idea to me. Clojure is a functional

Could you do this w/ a lazy seq cond? The seq terminates early if
cond x is met.

I'm not sure why you need this.

Thanks Brian.
For my own purposes, yes I have no need for a break or return
statement.

Hi,

Is it possible to implement this in Clojure? or any Lisp-like
language?
I've given it some thought and it seems it has to be a compiler level
feature.

You could implement Common Lisp-style return-from with a custom
exception class:
public class BlockException extends Exception {
String name;
Object val;
public BlockException(String name,

Thanks for the pointer! I haven't considered using Exceptions to
influence the control-flow. This will work perfectly.

For this to work, you'd first have to implement Common Lisp style
unquoting. :)
Heh, good catch :)
I've been switching between the two too much recently!
At least I didn't miss out the semicolons in the Java code ;)
