The structured macro paper referenced on the K wiki page also
seems rather interesting. A powerful macro facility needs to
be well integrated with the language (much like Lisp or
Scheme's macros) so that you can write for instance

critical_section(lock) {
...
bar:
...
if (cond1) break;
...
if (cond2) goto foo;
...
if (cond3) goto bar;
...
if (cond4) return; // from enclosing function
...
}
...
foo:


do you mean like C++:

do {
critical_object critical_instance();




}

No idea but I can not see how that will do what I had in mind. A purely
lexical translation of the snippet I gave above would be something like:

You can create an object on the stack that locks the mutex given
to it like so:

do {
mtx_lock_object mtx_locker(&lock);

}

When the object is destroyed by stack popping, the lock will be freed.

It's the same thing.
