(j3.2006) Question about implicit declaration

[Malcolm Cohen]

Sure,

 

module junk

  type t

    real(kind(x)) c

  end type

end

program test

  use junk

  implicit none

  x = 3

  print *,x

end

 

X is implicitly declared within the type definition, which effectively declares it in the module scope.

Subject: (j3.2006) Question about implicit declaration

 

8.7p4 says that if the outermost inclusive scope in which an entity
appears is not a type definition it is declared in that scope; otherwise
it is declared in the host of that scope.

Is it possible to declare the type of anything in a type definition
implicitly?

If not, what does "if the outermost inclusive scope in which an entity
appears is not a type definition" contribute?
