It would be nice to reduce warning noise (provided it is not too much trouble).
If and only if the warning is not bogus. Otherwise, it should be shut off at compiler level. MSVC is known to produce a few bogus warnings. For instance, GCC has -Wshadow. If you do that, you can't call a local variable "int y1;" because it will emit a warning as it shadows "double y1(double)" in math.h. So what, this is what I meant. I am sure the warning can be useful in many other contexts, but we can't ask people to fix the code for this.
Msvc 7.1 (warnings level 4, no language extensions aka strict) produces some warning 'noise' at:
const T operator*() const { return l.head(); }
"qualifier applied to function type has no meaning; ignored
A qualifier, such as const, is applied to a function type defined by typedef.
See DR295 (http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html#295). I think this warning is bogus.
However, this is a level 1 warning, so Microsoft obviously believe it is wrong C++.
It is, strictly speaking, but there is a DR for it. I'm not sure it's worth a code fix. pragma warning disable will do it. -- Giovanni Bajo
