I don't know. It was this way when I started working on it.
One problem is choosing a variable name.

We could even play some trick using "for" and a helper object to let
us write code like this:
 synchronized (foo)
 {
 ...
 }
(untested, with poor names)
 class helper
 {
	JvSynchronize sync;
	int count;
	helper(obj) : sync (obj), count (0) { }
	operator bool () { return count == 0; }
	helper &operator++ () { ++count; return *this; }
 }
 #define synchronized(Object) for (helper x (Object); ! x; ++x)
That might be too magical, not to mention slow.
