It isn't always equivalent. I also like to be aware of the layout of my 
structs. I just don't like padding and prefer to make use of that space; 
pack(1) provides an incentive to do that to avoid misalignment.

The example that you snipped showed how that could result in faster 
performance, likely due to the significantly reduced memory 
requirements, when the hardware complies.

Doesn't matter, as the i member is misaligned anyway. (Actually, around 
every 4th array element, i will be aligned properly.)

It's something you want to keep in mind. As I said, usually you will 
strive to keep elements aligned. And the x64 does need alignment in some 
areas (the stack must be 64-bit aligned; the ABI requires it to be 
128-bit aligned at call-points; and some instructions require strictly 
128-bit aligned data).

Then I'll cross that bridge at the right time. Since at the moment, the 
very common x64 and ARM64 architectures appear to allow misaligned 
accesses for most data, then that's not something I'm likely to have to 
worry about in my lifetime.

(I also concentrate on 64-bit targets. With mixed 32- or 64-bit, then 
pack(1) introduces some problems, as sometimes T* is 32 bits, and 
sometimes 64, screwing up your carefully crafted layout.)
