Normally in more mainstream C the nested "static void fn(Outer*);"
declaration would produce a diagnostic and instead what it (the compiler
and the code) seems to be doing is setting up allowing the call to compile
and once that is satisfied then the subsequent definition "has" to match
it, as perhaps a way to do type punning.
