Not at all, you're just not thinking the solution all the way through. If you want to see the results, an echo gets you there.

The important point though, is that one of the solutions moves you closer to a common language with other posix users, and one moves you farther away. If you use the tools the way they're intended to be used (brace expansion, for example), you'll recognize it when other people use it. You'll understand similar brace expansions in other commands you see others craft. You won't need to remember if that shell you sudo'd into uses your override or not. The reasons go on forever.

It really isn't necessary. That's not to say someone can't think of a reason for it, but rather that there are better ways to do what it does.
