In your example are at least two errors.

T(t); -- the "t" is not defined there
public T opCall(int[] i) { -- it should be called as t(i), if you want 
call T(i), make this method static.

I personally do not encounter problem you are writing about. But you 
should be aware of: Expressions that have no effect, like (x + x), are 
illegal in expression statements. If such an expression is needed, 
casting it to void will make it legal.
