Recently I've hit a problem with collections in C#. Given classes
class A {}
class B {}
And two collections Collection and Collection it's possible to concat
them into an array A[]. The efficient way to do it is to use CopyTo(T[],int)
method, but it accepts only array of exact collection item's t

For interfaces, the compile time checking is limited to verifying that functions
with the right signature are supplied. Templates can go considerably beyond that
with the constraint checking.

ensure reduced coupling, thus enabling the use of mock classes for unit tests

A long discussion on the utility of interfaces has taken place on the
announce newsgroup following my announcement of dcollections for D2.
Dcollections supports interfaces peripherally. Meaning the types in
dcollections are essentially concrete classes with interfaces tacked on

That's exactly what the zip is. Unzip it and go. To uninstall, just
