What did you do?
v run . (assuming test.v and valiant.v are in the same folder)

valiant.v:

module valiant

pub struct ReqInfo {
	path string
	params map[string]string
}

pub enum ReqType {
	get
	post
	put
	delete
}

pub struct Server {
pub mut:
	routes map[ReqType] map[string] fn()
}

pub fn get(mut val Server, path string, func fn ()) {
	val.routes[ReqType.get][path] = func
	println("added")
	println(val)
}

pub fn post(val Server, path string, func fn ()) {
	
}

test.v:

module main
import valiant

fn main() {                                                   
    mut server := valiant.Server{}
    valiant.get(mut server, "/", fn () {

    })

    println(server)
    server.routes[valiant.ReqType.get]["/"]()
}

What did you expect to see?
the library i was working on

What did you see instead?

(Use `v -cg` to print the entire error message)

builder error:
==================
C error. This should never happen.

This is a compiler bug, please report it using `v bug file.v`.

it errors on the last line in the main function in test.v

Nested maps access to function execution problem.
Simpler example of the problem (and a work around for now).

fn main() {
	mut smap := map[string]fn (){}
	mut dmap := map[string]map[string]fn (){}

	smap['one'] = fn () {
		println('One')
	}
	dmap['one']['de'] = fn () {
		println('Eine')
	}
	dmap['one']['jp'] = fn () {
		println('Ichi')
	}

	smap['one']()

	// dmap['one']['de']() //throw compile error
	temp := dmap['one']['de']
	temp()
}

thanks, i appreciate the helpful example
