Le samedi 19 janvier 2019 14:47:19 UTC+1, philippe= .....@free.fr a =C3=A9crit=C2=A0:
In a C ++ class when you have a lot of methods temp= lates with the same types, you have lot of redundant information.
for example :

class Foo=C2=A0
{
public :

=C2=A0 =C2=A0=C2=A0 template <typen= ame T>
=C2=A0 =C2=A0=C2=A0 void meth1(T t);

=C2=A0 =C2=A0=C2=A0 template <typename T>
=C2= =A0 =C2=A0=C2=A0 void meth2(T t);

=C2=A0 =C2=A0 template <type= name T, typename U>
=C2=A0 =C2=A0 void meth3(T t,, U u);
}:

Could not imagine something like= this :

class Foo=C2=A0
{
public :

=C2=A0 =C2=A0 =C2=A0 methods <typenam= e T>=C2=A0
=C2=A0 =C2=A0 =C2=A0 {
=C2=A0 =C2=A0 =C2= =A0 =C2=A0=C2=A0 void meth1(T t);

=C2=A0 =C2=A0 =C2=A0 =C2=A0=C2=A0 void meth2(T t);
= =C2=A0 =C2=A0 =C2=A0 =C2=A0=C2=A0 template=C2=A0 <typename U>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 void meth3= (T t,, U u);
=C2=A0 =C2=A0 }:
}:

What do you think about this ?Is there a proposal that goes in this direction ?
Problems wi= th parser (compiler front end , Doxygen =E2=80=A6) ?

Indeed, there is the same problem with template = functions outside classes. A more general solution would be more appropriat= e.
