just for reference,

Sun's java compiler seems to do exactly that, see SEARCHING FOR TYPES in
http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html

Example: have these mutually dependent classes (each in its own file)

class A { static B foo () { return new B (); } }
class B { static A foo () { return new A (); } }

and you call  "javac A.java" (or the other) then it compiles both.
