// hash.d. This is part of a library, not the application. Therefore, it // is in the import path but is not explicitly passed to DMD struct HashRange(K, S, ) { size_t _length; this(S* set) { this._length = set.length; } } struct StackSet(K) { HashRange!(K, typeof(this)) elems() { assert(0); } @property size_t length() { assert(0); } } // a.d. This is part of the application. import hash; // b.d. This is also part of the application. import hash; void fun() { StackSet!string alreadyDone; } $ dmd -c a.d b.d hash.d(11): Error: struct hash.StackSet!(string).StackSet no size yet for forward reference hash.d(5): Error: cannot implicitly convert expression ((*set).length()) of type size_t to ulong hash.d(13): Error: template instance hash.HashRange!(string,StackSet!(string)) error instantiating b.d(4): instantiated from here: StackSet!(string) b.d(4): Error: template instance hash.StackSet!(string) error instantiating

Seems to be fixed before 2.066.1-rc2 (tested on 64-bit Linux). I was unable to build older releases with Digger: 2.054 fails to build and 2.060 can't find object.d.
