Why the get_tracer function is returning a string instead Tracer object

[Rodrigo-Novas]

I have a question about a function that is inside the tracer for the Otel sdk with python technology

This function is specifying the return of the type Tracer as an string

get_tracer

Shouldn't it be something like this?:

    def get_tracer(
        self,
        instrumenting_module_name: str,
        instrumenting_library_version: typing.Optional[str] = None,
        schema_url: typing.Optional[str] = None,
    ) -> trace_api.Tracer

Yes, that particular case can (and should) be changed. Notice that sometimes we have done that because we are trying to return a symbol that has not yet been defined and PEP484 says a string can be returned in that case.

Apparently we can resort to from __future__ import annotations to bypass that problem.
