Of course, this is all a consequence of the well-known failure of
natural language: verbs come before their objects.  It is thus natural
to write f(x), when in fact it is the object that should come first, not
the function.  Switching to a (natural) language where (finite) verbs
come at the end of sentences, where they belong, should fix this issue
in time.  Doing the same in a functional language would be ideal as
well, but might limit its use among those who speak inferior natural
