Hello,

I think that what you want is implemented with the Unshared field:

https://github.com/sarulabs/di/blob/master/definition.go#L10

It is not very well documented though. I'll see if I can improve it.

https://github.com/sarulabs/di#object-retrieval

By default the objects are shared that means what they stored as singletons in the Container. You will retrieve the exact same object every time you call the Get method on the same Container. The Build function will only be called once. In case when you don't want the objects to be shared set the Unshared property of object definition to true.

EDIT:

go get github.com/sarulabs/di/v2

in the code

import (
  di "github.com/sarulabs/di/v2"
)

Saying that as a go newbie, what is

go get github.com/sarulabs/di

supposed to point to? Should it point to the latest v2 without me explicitly asking for it.
i.e. what is github.com/sarulabs/di v2.0.0 supposed to reference?

----

Nice, that is what I needed however what is published does not have that fix.

go mod init ditest
go get github.com/sarulabs/di

module ditest

go 1.16

require github.com/sarulabs/di v2.0.0+incompatible // indirect

definition.go

package di

// Def contains information to build and close an object inside a Container.
type Def struct {
	Name  string
	Scope string
	Build func(ctn Container) (interface{}, error)
	Close func(obj interface{}) error
}

// DefMap is a collection of Def ordered by name.
type DefMap map[string]Def

// Copy returns a copy of the DefMap.
func (m DefMap) Copy() DefMap {
	defs := DefMap{}

	for name, def := range m {
		defs[name] = def
	}

	return defs
}
