The surprising part to me is that non-@safe main doesn't infer
anything. Is that true?
They aren't auto functions or templates, just normal member functions of
a struct in main. I thought inferring function attributes was only for
auto functions and templates. I never thought it would for member
functions of structs in main. But yeah, I'm pretty those functions are
@safe and not @safe @nogc nothrow pure.
Logically, any internal struct's code is available for examination
wherever it could possibly be used. If it's returned, then the function
return must be auto (and the function code available). If it's passed as
a template parameter, it is available.
Inference could happen on any internal function anywhere, not just
inside internal structs.
I'm not sure why the marking of the enclosing function should make a
difference, either they all infer or they all don't infer. To me, this
seems like a bug (the inconsistency).
