Actually I personally do have a use case for the argument names being
available, but I wouldn't be too surprised if I was one of the few ones
that actually needed it. In my case I have some code that builds
definitions of Ruby methods and such, including the argument types and
names. An example of the result of this can be seen here:

Having said that, we seem to mostly agree so I'll try to not deviate
from the subject any further :)
