No it isn't. Google QueryInterface(). Nobody lists all the
interfaces at the top level functions, which is that Rust
traits and C++ concepts require.
The only time you don't use the right interface for your needs
is if you plan on casting somewhere down the line. But
certainly there are people who don't do that, I for one feel
it's bad practice to need to use casts to circumvent the type
system like that.
I confess that I've always thought that QueryInterface was a
_horrible_ idea, and that if you need to cast your type to
something else like that, you're doing something wrong.
*shudder* I really have nothing good to say about COM

Well yes and now. When you design is new and shinny, sure, that
is a sign that somewhere it is broken. When you are patching a
hundred of thousand line of code, you may not be able to get the
refactoring in all at once in a realistic manner and need to
build some debt. Hopefully, as the refactoring progress, these
hacks are removed, but not having just makes cost of change
prohibitive, which is bad.
