In a C ++ class when you have a lot of methods templa= tes with the same types, you have lot of redundant information.
f= or example :

class Foo=C2=A0
{
public :

=C2=A0 =C2=A0=C2=A0 template <typenam= e 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 me= th2(T t);
=
=C2=A0 =C2=A0 template <typename 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 <typename 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 meth= 3(T t,, U u);
=C2=A0 =C2=A0 }:
}:

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