Error message for dummy procedure argument.

[caguerra]

In the following module example, declaring implicit none to detect implicit types for variables like "x" generates the following error message for the dummy procedure f: "No matching declaration found for argument "f"". Also, if the type declaration of "x" is uncommented then the warning message "Variable "x" masks variable in parent scope" appears, for variable "x" in the interface.

module test

    implicit none 

    contains

        subroutine foo(f)

            interface
                function f(x)
                    real, intent(in) :: x
                    real :: f
                end function
            end interface
            !real :: x

            x = 1.
            print*, f(x)

        end subroutine

end module

I am also seeing this issue in my fortran subroutines that take interfaces as dummy arguments.

I have the same issue.

Okay so I finally got some spare time and have a fix for this. I will open a PR but given that the repo hasn't been updated in more than a year I will most likely be authoring a fortls2 or a dev version of fortls so people can start using a more up to date version.
