--- Comment #1 from Iain Buclaw <ibuclaw at gdcproject.org> ---
1. Lambdas that don't have any non-local access are implicitly typed as
function pointers.  So the equivalent nested function would be:

static void fun(Value)(Value _) {}

2. Template function literals are special in that they are implicitly enclosed
in their lexical context.  Nested function templates are not enclosed, and so
cannot access the surrounding frame when instantiated non-locally.
