title: Performance and practice of lazy regex?
body: <p>I <em>read on the internet</em> i should avoid lazy regex because of 'worse' performance and 'bad' practice. I never seen an example of either. I havent heard of an app that is CPU bound by its regular expression. Others say they 'learned' to avoid it but never mention why while one hinted it was because of usual side affects when turning on or off flags in older programs.</p>
  
  <p>Are there a reasons to avoid lazy regex? If so what are they?</p>
