No (or at least not yet :-) depending on how we encode the model and whether we only encode the model there might be an initialization hit on first invocation to generate the bytecode, that could be ameliorated at link time and/or with Leyden. Details to be
worked out…)</div>

To be clear it *does not* broaden. e.g.,</div>
<div><br>
</div>
<div>final int i = a() + b();</div>
<div>@Reflect</div>
<div>Runnable r = () -> IO.println(i);</div>
<div><br>
</div>
<div>We don’t broaden the scope to reflect over the declaration of local variable i and its initializer expression.</div>

<div>“this" is a final variable that is captured. The fields themselves are not captured.</div>
