This compiles and outputs 5.

I believe dup should statically fail...

...is one that has no inputs or outputs.

In my mind it is not buggy...

...Foo!double B;
alias Foo!int A;

outputs

Boo!(double) Boo!(double)

while it should...

auto bf = new BrainFuck();

writef(bf.toString()); // outputs "Hello World!\n"

    {
        writeln("inside loop %d", i);
    }
}

Currently outputs nothing, it should output:

outputs:

This is understandable as B...

...escape analysis has N inputs and M outputs.  Annotation is going to be very hard...

Outputs "foo()", but shouldn't it just be...

...is "A::x()", but with -inline, it outputs "B::x()".
Conclusion: the dmd inliner must...
