This is good stuff to have "in the toolbox," however habitually organizing structs this way is premature optimization. Much better to sensibly organize the fields and ignore alignment entirely unless you have a really good reason to do this. Good reasons could be that you know you will create a lot of these objects, or it has become a performance issue due to cache misses this would improve.
