[11:55:12]  <@dandean>	 Found an incorrect variable declaration in that last PR. Caught it in canary!
[11:55:15]  <@oscar>	 mimi, its an experience
[11:55:22]  <@dandean>	 Fix is going to canary right now.
[11:55:25]  <tOm>	 WRITE A REGRESSION TEST
[11:55:49]  <@oscar>	 YEAH! If the tests didnt catch it, your tests gotta be better
[11:56:35]  <@dandean>	 you are correct sirs
[11:56:53]  <@oscar>	 tom and I are sitting our desks chanting "tests tests tests tests"
[11:56:54]  <@dandean>	 it's in a controller template helper – those can be a bit annoying to test.
[11:57:01]  <whilp>	 the noise is deafening
[11:57:07]  <whilp>	 all of alder is yelling "TESTS"
