[cmd] Undeprecate deferredProxy #7417
Conversation
This changes the way deferred proxy is implemented to not use the deprecated ProxyCommand constructor. This function serves a good purpose that should be kept IMO. The constructor was confusing but this is just good syntactic sugar over `defer(() -> supplier.get().asProxy())`. Signed-off-by: Jade Turner <[email protected]>

I couldn't make this work using the AsProxy decorator

Since the return of supplier() is already an rvalue, the move isn't needed.
The following should work:
return supplier().AsProxy()(You can also pop a ToPtr there in between, but I think it's unneeded)

Oh I missed that we're dealing with a Command* and not a CommandPtr.
Never mind.

I don't think there's a non-owning version of AsProxy(), so yes, I think this does have to be via the constructor. Maybe just add a comment explaining that so we don't forget?
