I actually agree it is a bit questionable, but I think the
difference is += is, conceptually at least, atomic - it is a
single function, append() instead of two calls,
set(calculate()).
Isn't that a compiler implementation detail though?
I always considered a+=b as a shorthand for a=a+b so I find this
surprising and a bit confusing.
Maybe I need to revise my thinking on this :)
