Const vs Non const method

Check this simple code:

I can't understand how to minimize code duplication for function 
like get().
Of course on real case body is much bigger and complex than that.

The only way I found is to move the body of function inside a 
mixin template:

mixin template getterImpl()
{
    auto getterImpl() { /* very long body */ return inner; }
}

and then:

auto get() const { mixin getterImpl; return getterImpl; }
auto get() { mixin getterImpl; return getterImpl; }

Am I missing something? I don't think it's the right way.
