1/ @hasen_95dx
@nicbarkeragain
this particular case though is easily solved with defer or even closures
Container(...., func() {
// container is closed when this func exits
})

Yes, I tend to use the “single iteration for loop” macro trick in C to do this exact thing with scope, but there are still a bunch of cases where you might want to have a direct API that you can use to call open / close:

I’ve also found explicit open / close to be very useful in rendering tree views / arbitrary recursive hierarchy etc.

Right. With the closure approach it would have to change.
body := func() { … }
if condition { Container(…, body) }
else { body() }
