But what compiler does with this function? How `void` appears
in the error message?
There are no arguments used thus `to` is resolved as plain
template symbol, not a function. Template that does not resolve
to any valid entity is treated as if it had type 'void' in error
messages, even if it is not technically true.
Why does it even picks this function? `to` has required
argument, apparently it can't be called without one.
When you shadow some symbol with a new declaration in more
"local" scope, it gets shadow completely, not just added to
overload set. No matter what arguments are used only the new
symbol will get used.
