I would put this differently. 'apply' is a just another generic tie-in
(see http://www.aldor.org/docs/HTML/chap11.html) like 'bracket'. And
juxaposition always denotes application (that's semantics!). See
http://www.aldor.org/docs/HTML/chap4.html#6 No syntax involved here at
all. But I guess it doesn't really matter what you call it unless you
are the compiler writer. :)
