proposal: lazy initialization

[betula]

The main reason: The decrease in result application bundle size.
If I can use lazy initialization, I can make isolated scopes and clear the state whole the app.

const b = box(0);
const n = wrap(() => get(b) + 1);

on(n, v => console.log('next', v);

// All of it should be lazy

I should deny of subscription to function expression, for example:

on(() => get(n), v => console.log('next', v)) // deny, no possible to make lazy subscription

After I can add the new function in a separate folder.

isolate(async () => {
  await runApp();
});

After remini can be used without dependency injections or providing service. Just standard modules!
