Good grief, man!  Why didn't you just say that to begin with?  I'm 
sitting over here, questioning my [in]sanity.  ;)

Well, I assumed that `\etc` was your personal shorthand in snippets for 
"manually put whatever you want here", like an ellipsis.  Of course, I 
had no reference to know that `\etc` was (or soon will be) actual valid 
syntax.

But it is great to hear that `\etc` will eventually be a thing, as it 
should help reduce the need to switch to Scheme for this type of thing.  
Will this convenient syntax support more than one argument, or is that 
beyond the scope of the feature?
