Howto assign a variable or value to yaegi?

[andig]

Proposal

First, please excuse me for asking here. https://community.traefik.io/c/yaegi seems a dead link and the community page doesn't have a yaegi section. Please close if inappropriate.

Background

I'd like to

a := "foo"
interp.Set("pkg.Vars.B", a)

instead of

interp.Eval("pkg.Vars.B := \"foo\"")

which requires individual handling per type. Set could follow Go's assignability rules.

Workarounds

Use Eval()

What would it take to implement something like this? While Evaling is straightforward for simple types it gets much more ugly and may require additional parsing with e.g. assigning a time.Time. It would be really nice to do this from an already initialised time.

Just stumbled again across

if _, err := vm.Eval(fmt.Sprintf("ts = time.Unix(%d, 0)", ts.Unix())); err != nil {
	return 0, err
}

which could become

interp.Set("pkg.Vars.ts", ts)

and save the round trip. I've looked at the yaegi sources but couldn't find a good starting place.
