An example would be looking for the first occurrence of a string in each line of a text file. You would still need the while loop, but once you found the string in the line you just read, you could either break or return.

I'm not opposed to early exits from a loop if doing so simplifies the code. Sometimes you can just return.

| Apr 19, 2016 at 18:27 | comment | added | candied_orange | That one's a classic. Would you ever suggest using a break? | |

Nice. There are times when you need to do A and B in order with a test T exactly between them. The usual A T(B A) priming pattern does this but duplicates A. Any general alternatives to this general pattern?
