Comment:
The C++ standard specifies plenty of cases of more or less obscure
behavior and I doubt that even among seasoned developers many know them
all. The evaluation order of function arguments might be one of the more
popularly known one, but it still is not exactly obvious and I'm sure a
good percentage of developers isn't aware of it. Combined with the fact
that `this` is treated like a regular function argument, I think the
percentage is even higher.
While I generally agree that we don't need to document such an C++
standard oddity, I think in this case we should. The layout builder API is
intentionally designed to result in potentially long expressions that read
like linearly processed statements. So the mistake of assuming linear
evaluation is easily made and warrants a word of warning in the
documentation IMO.
