Yes, this is how C++ works. There is no template argument deduction from
constructors.

Bummer. I wonder why? I suppose the workaround is an inline helper function
wrapping the constructor, plus a couple of calls on the copy constructor...

In particular, template arguments are _never_ deduced for types, only for
functions.

So a constructor counts as a type for deduction purposes? I'd always thought of
it as a function, albeit a peculiar kind of one. It's the parentheses I suppose
:-)

A constructor is a special function the name of which is that of the type
to which it belongs. The type's name is that that includes template arguments.
You could also say that the constructor is a function
