/**
* This test demonstrates a change in behavior when streaming print directives are in use, they
* can elide some runtime type checking. This is because the compiler explicitly puts in {@code
* checkcast} instructions whenever calling {@link SoyValueProvider#resolve} (see every caller of
* {@link ExpressionDetacher#resolveSoyValueProvider(Expression)}). However, when we are able to
* stream a soy value provider we can't insert a {@code checkcast} instruction because we never
* actually calculate the full value.
*
* <p>We could change SoyValueProvider.renderAndResolve to accept a TypePredicate and we could
* sometimes enforce it, but for the time being this isn't happening.
