Not possible for templates.

Also, an answer like "just use a .di file" is going to be a really hard 
pill to swallow.

I think a mechanism to prevent one from using the name of a specific 
parameter for a call would be much more appreciated. Either parameters 
of a specific pattern, or make official the usage of implicit parameter 
names (i.e. _param_0)
