we must get our big red letters and write somewhere: "template is not
XXX", where XXX is anything of function, method, struct, class, etc. ;-)

eponymous template syntax make people believe that `a()() {...}` is a
function, while it's not. this is template, and it has template magic in
in.

this is not your fault though. this is not a fault of anyone for that
matter: it was designed to look like function, so it does. alas, we
can't have it looking as a function and not confusing newcomers in the
same time.

eventually you will start to easily recognize such "non-XXX" templates.
i daresay that D is all about templates, so you have no other
choice. ;-)
