I would suggestion using some kind of wrapper instead of doing
true monkey patching. Example:
class Wrapper
{
private Object o;
this (Object o) { this.o = o; }
auto opDispatch (string name, Args ...) (Args args)
{
// Use this function to "catch" all calls and forward
as necessary to "o"
}
}

That's a reasonable option too. I think I'd rather use deject.
The problem I'm trying to solve (and maybe this isn't as
important as I think) is that DMocks or deject + DMocks only
works on a subset of the language. I can't mock out free
function calls, private or final methods, or functions on
structs or unions (can I inject mocked structs using deject?).
What do I do when I want to mock out std.stdio or std.random?
The solution would be to use tools like in C++/Java/.NET world
that rewrite assembly/bytecode and replace method/function calls
with your mocks.
It works most of the time.
