this not known at compile time. replace s with this and it works! 
s is an argument which is also not known at compile 
time(generally).

Should work with this.

Just "simplifying"

this.foo();
s.foo();


(obviously more complex code)

Do you trying to do a recursive call from foo to itself?

foo has nothing to do with it, as I said, removing it produces 
the same error['p.foo(); // Fails even if this line is removed']. 
I only put in something in the block because some blockhead would 
say something if there was nothing there like "Why are you even 
bothering with a static for each on an empty block? are you that 
stupid that you don't realize the compiler won't emit any code?".

To expand on Michelle's cryptic response, the second form (using 
`Alias!this` instead of `this`) DOES work!

I think this is a bug. If the latter works, the former should. Please 
file at issues.dlang.org with a complete example.
