#java

1. 15:16 dreamreal gah, I hate reading stuff where I'm left going "... wait, why is this new? $foo has had that for a while now, that particular syntax looks okay but how does it... OHHH. Ew."
2. 22:23 jreicher dreamreal: why is what new?
3. 22:24 jreicher On a different note, I just did something I never thought I would do. A deliberate upcast so that the compiler can verify a caller won't do something to the returned object.
4. 22:24 jreicher (Not without being naughty, anyway)
5. 22:26 ernimril uh? is doing a cast being naughty?
6. 22:34 jreicher Not an upcast. Not at all.
7. 22:35 jreicher In fact you couldn't avoid them before covariant return types were added to Java.
8. 22:35 jreicher That's an implicit upcast every time, right there
9. 22:36 jreicher And actually is what I'm doing now. This method is "explicitly non-covariant"
10. 22:36 jreicher Hardly ground breaking, but it never crossed my mind I would want something like this.
