Overloaded functions

[gnikit]

From the original repo See: https://github.com/hansec/fortran-language-server/issues/135

The solution that I have in mind is to use the function's/subroutine's signature help (--use_signature_help) to distinguish between different instances of an interface.

• When typing the function/subroutine name it should show the number of "overloads"
• When typing the argument list it should be able to filter through the overloads available throughout the project
• When hovering over the fully typed expression it should show only a single definition, matching to the function/subroutine
• Ideally we should be able to show the hover message with those little arrows that allow you to navigate between different defs
• TODO: make sure that the autocomplete of an overloaded interface will autocomplete to the interfaces name and not the name of the function/subroutine chosen from within the interface

Hi @gnikit,

I was going to report this issue, but discovered this GitHub issue. I noticed this feature seemed to be missing; something I took for granted over in CodeBlocks (cbfortran).

I've attached an example that has a slight twist in that I define a class and a generic interface named the same as the class. The interface is to a variety of constructor functions for the class.

Feel free to use. If there is any way I can help, I'd love to.
