Should you be compelled to put it after @filenames? (eg 
@filenames(whatever)[*]) to indicate that you are passing multiple things?

It also looks icky from a type system perspective - what is the type of 
a[*] and how is that distinct from a? Its a (undocumented and unchecked) 
mysterious ordered sequence type that you can only use specifically in app 
parameters and a few other places, that there is not much to handle and 
that you should pretend doesn't exist...
