Yes, I saw something about that when I googled for the answer, but I
just didn't understand that subshell thing (maybe because my native
language is not English). Seems like it creates a separate process.
Does this mean that what's in the parentheses is executed at the same
time as ”DoSomethingElse” in this case? Could that be a bad thing in
some cases?

Another obvious solution would of course be to create a function that
does everything inside the parentheses, and just call it on a single
line, but that was not what I was asking about.
