Go is stringly typed, right?

stringly.go

package main

import (
	"fmt"
	"reflect"
)

type (
	MyFirstEvent  struct{ AccountID uint64 }
	MySecondEvent struct{ AccountID uint64 }
)

func main() {
	first := MyFirstEvent{AccountID: 123}
	second := MySecondEvent{AccountID: 456}

	var (
		firstID  uint64 = RuntimeGet[uint64](first, "AccountID")
		secondID uint64 = RuntimeGet[uint64](second, "AccountID")
	)

	fmt.Println(firstID, secondID) // 123 456

	RuntimeGet[uint64](first, "Unsafe") // panic: reflect: call of reflect.Value.Interface on zero Value
}

func RuntimeGet[T any](v any, field string) T {
	return reflect.ValueOf(v).FieldByName(field).Interface().(T)
}
