Anonymous generic function inside of a generic function

[Dracks]

Describe the bug

Code: https://vosca.dev/p/fb9c42f729

When you have a generic function that accepts two types, and has an anonymous function inside, If you put only one type (and not the second, as this case that is used both), it give you a weird error.

I hope the people that knew better V-lang, can explain better the problem

struct Test{
	something string
}

struct Dependency {}

struct Factory {
	build fn()!
}
fn  inject[T](mut serv T)!{
	$for field in T.fields {
		if field.typ is string {
			serv.$(field.name) = "Hello world!"
		}
	}
}

fn use_factory[F, E](factory fn(dep F) !E) Factory{
	return Factory{
		build: fn [factory][F]()!{
				mut dep := F{}
				inject[F](mut dep)!
				dump(factory(dep)!)
		}
	}
}

use_factory[Dependency, Test](fn (dep Dependency)!Test {
	return Test{
		something: 'daleks!'
	}
}).build()!

Expected Behavior

Complain that the anonymous function misses the second generic parameter

Current Behavior

Output:

code.v:11:16: error: unknown type `F`
    9 | }
   10 | fn  inject[T](mut serv T)!{
   11 |     $for field in T.fields {
      |                   ^
   12 |         if field.typ is string {
   13 |             serv.$(field.name) = "Hello world!"
If the code of your project is in multiple files, try with `v .` instead of `v code.v`
Exited with error status 1

Reproduction Steps

For what I found you need a function, that creates an anonymous function that handles both types
