Yes, I'm afraid that's what it looks like (eek!).  The fact that tcc can now 
correctly handle that test case is a good sign.  The _compiler_ should be nice 
and clear, but at least some of the _test cases_ should be evil (so that we can 
wring all the bugs out).

> Return value is a pointer to a function "void blah(void)";  Check, I think.  

To be fair, this isn't one of C's better areas.  Some other languages' 
notations make this kind of declaration easier; every language has its +s and 
-s.

Funny you should mention that, I've defined a variant of LISP s-expressions 
called sweet-expressions which lets you use indentation, traditional 
function-call notation, and infix while still retaining the usual 
program-as-data advantages of LISPs (including macros, comma-lifting, etc.):

But anyway...
