Why would they need to change the name of a function argument 
anyway?

Note that the name is already exposed in the documentation too, 
as well as by existing reflection (I, among others, have written 
named param libraries already, for example).

I'd probably not use it myself so I'm meh on having it in the 
language... but I don't think the breakage is a big deal. You can 
just not use it in your code and be protected against arbitrary 
changes.

Though if the name changes, it might indicate a change in meaning 
of the param too, so maybe breakage is a good thing.
