return results instead of callback

[TheColorRed]

Is there a way to allow for results to be returned to a variable instead of posted through a callback?

var conn = mysql.createConnection({...});
var rows = conn.query("select * from my_table limit 10");

passing the results to a callback is nice, but not always needed and/or wanted.

No; this is a limitation of Node.js. Network calls must always be async.

@dougwilson I believe that we can just use yield to solve that problem.

Whatever we do has to work in Node.js 0.6, 0.8, 0.10, and 0.12. As far as I know, yield only exists is 0.12+, so it's not usable here. Someone more familiar with yield can chime in, or feel free to make a PR (our CI will validate it works in our supported Node.js environments).
