Of course that generates a linker error. You just declared a
function without
a body.

sure, but it's a bit unexpected. do we need to be able to declare
empty functions?
It can be useful at module scope, and it would complicate the grammar to make
it anything else at function scope, even if there's no practical reason to use
it that way there. C/C++ (which doesn't have nested functions) also treats
that declaration as a function declaration.
but whats even more confusing: you are not allowed to declare an
no_arg constructor. but you are allowed to declare one where all
parameters have default parameters. but then, how to call it
without args? auto k = S(); doesn't work?
It's a bug. I'm pretty sure that there's a bug report for it already, but I'd
have to go digging for it to know which one it is.
