I disagree with your disagreement. :-)  Gordon Sande and Richard Maine
also disagrees with you (see c.l.f threads "I've never seen this
before in 30 years - what is this?" and "What is this").

>From Fortran 95, Sec. 12.5.4, lines 38 and 39:

  The dummy arguments have a scope of the statement function.  Each
  dummy argument has the same type and type parameters as the 
  entity of the same name in the scoping unit containing the statement
  function.

Note, this passage does not include rank.
