can using auto break the return type

[silent lion]

constexpr decltype(auto)
Reset(const typename Traits::Type& arg)
{ auto ret = Fun(); val_ = arg; return ret; }

I want this member function to return value of the same exact type that Fun returns

can auto ret break it?

like auto return type instead of decltype(auto) breaks

[somber tangle]

well as always it depends on what Fun returns

but decltype(auto) is the safer choice yeah

[silent lion]

oh, now I realised I can apply decltype(auto) for a variable as well as for a function

I thought it was only for functions

thanks
