[13:50] dash: akesterson: mmm, nope, exceptions work like normal
[13:50] akesterson: see the gist, no they don't. Not in 2.6 and 2.76
[13:50] akesterson: s/2.76/2.7/
[13:50] dash: akesterson: yes, that's exceptions working like normal
[13:50] dash: akesterson: as soon as the raise statement is run, the exception is raised
[13:51] dash: akesterson: calling a generator function creates a generator object but doesn't run anything in the function body
[13:51] dash: akesterson: that happens when the generator is iterated over
[13:51] akesterson: dash: I see
[13:51] akesterson: that makes more sense and enrages me less
[13:51] dash: akesterson: so, 'wat()' does not raise an exception because the raise statement hasn't been run yet
