suggest parameter names

[michaelkonecny]

Fortran supports passing arguments via their names. For example, this function:

subroutine mysubroutine(arg1, arg2)
   integer, intent(in) :: arg1
   integer, intent(in) :: arg2
   !...
end subroutine mysubroutine

can be called like this: call mysubroutine(1, 2) but also like this: call mysubroutine(arg1=1, arg2=2) where the order is not relevant: call mysubroutine(arg2=2, arg1=1)

Using the argument names can sometimes really improve code readability.

It would be nice, when one's cursor is inside the function call brackets, to get autocomplete suggestions for the argument names (arg1, arg2).
