That's why I put the severity as enhancement :)

I thought of a better example.

template<bool force_inline>
void __attribute__((always_inline(force_inline))) foo()
{
    // ...
}

Now you can choose whether to force inlining of foo on a per call site basis,
which AFAICT there is no way to do in GCC currently. I don't think template
specialization can accomplish the same -- the best you could do would be
defining a function with a copy pasta of the same code but a different name.
You couldn't have both versions call a common function because the force_inline
parameter would need to apply to it as well.
