import : warning err

[Avey777]

Describe the bug

import warning err

Reproduction Steps

log_project/strcuts/struct.v

module structs

import veb

pub struct Context {
	veb.Context
}

log_project/middleware/logger.v

module middleware

import log
import structs { Context }

pub fn logger_middleware(mut ctx Context) bool {
	log.info('[veb] trace_before_request: ${ctx.req.method} ${ctx.req.url}')
	return true
}

log_project/main.v

module main

import veb
import structs { Context }
import middleware { logger_middleware }

pub struct App {
	veb.Middleware[Context]
	veb.Controller
	veb.StaticHandler
}

pub fn main() {
	mut app := &App{}
	app.use(handler: logger_middleware)
	port := 9009
	veb.run_at[App, Context](mut app,
		host:               ''
		port:               port
		family:             .ip6
		timeout_in_seconds: 30
	) or { panic(err) }
}

Expected Behavior

no warning

The problem still exists

[fleximus]

Here's how you can fix the warning:

1. import middleware
2. app.use(handler: middleware.logger_middleware)

Someone else still needs to decide how to handle this condition. I can think of removing the warning or, maybe better being more strict and give a compile time error.

dto/user/user1.v

module user

pub struct User1 {
	id string
}

pub fn user1() {
	println('Hello, user 1!')
}

parts/user/user2.v

module user

pub struct User2 {
	id string
}

pub fn user2() {
	println('Hello, user 2!')
}

main.v

module main

import dto.user {User1}
import parts.user as user2 { User2 }

fn main() {
	user.user1()
}

struct User {
	id  User1
	id2 User2
}

main.v:4:8: warning: module 'user2 (parts.user)' is imported but never used
    2 |
    3 | import dto.user { User1 }
    4 | import parts.user as user2 { User2 }
      |        ~~~~~~~~~~

    6 | fn main() {
Hello, user 1!

Here's a simpler example, so I think it's right not to issue warnings
