templated function call from interface

[rumbu]

interface I
{
     void foo(T)(T t);
}

class C: I
{
}
//bug 1: compiler does not complain about the fact that C doesn't 
implement foo(), even if C is instantiated somewhere.

void bar(I i)
{
     i.foo(2);
}
//bug 2: Error 42: Symbol Undefined 
_D4main1I10__T3fooTiZ3fooMFiZv (void main.I.foo!(int).foo(int))

I suppose that these two are related.
Are these bugs or it's not possible to have templated functions 
in an interface?
