Yes, but you can minimize the risk. Particularly if you are importing your own modules. Just need to use some common sense.
If you are referring to importing at the block level, I see a lot of Rust code doing that including in the compiler. Glob imports are not really used though. Like most people, I’m not sure how I feel about them yet. Eric On Mar 12, 2014, at 2:45 PM, Bob Ippolito <[email protected]> wrote: > Is that what people actually do?
