Not detecting classes when they become available

[johnspackman]

If a class is not available then a "Unresolved use of symbol foo" is reported, but if that class is subsequently created (eg a git checkout or editing the code) the compiler will not detect the new class; it is necessary to touch the class which had the "Unresolved use of symbol" error to force the compiler to recompile it and detect the dependency.

Simpler solution: What's about detection new files and start recompile?

[johnspackman]

that would mean forcing a full recompile of all files every time a new class is added, in case they refer to the new class; instead, we could make it so that the class which has a 'Unresolved symbol' lists that symbol as a dependency (assuming that it looks like a class name), so that when it is available it can be loaded

then it's your task to implement :)
