In more complex cases, initializers need to run arbitrary code before
assigning initializers to fields. While this is possible using the
underscore codeblock feature (`_: {}`), values returned by such
functions cannot be used from later field initializers.
The two new functions `[pin_]init_scope` allow users to first run some
fallible code and then return an initializer which the function turns
into a single initializer. This permits using the same value multiple
times by different fields.
