I just saw a use of "come away" below, and felt that the phrase is rather strange. It seems almost malfunctioning because "come" suggests moving towards the current location and "away" suggests well, moving away from (or leaving) the current location. More "compatible" combinations seem to be "go away" or "get away"..
How is it that these two can be put together ("come" and "away")?
we will attempt to introduce error handling one piece at a time so that you'll come away with a solid working knowledge of how everything fits together.
Suppose the above is in a lecture, are you coming or leaving the place when you "come away with" something? Any historical origins for the usage?
