What's the right way to pass form element state to sibling/parent elements?
... No problem. I actually went back after writing this post and reread some of the documentation, and it seems to be inline with their thinking and best practices. React has truly excellent documentation, and every time I end up wondering where something should go, they typically have it co...

Removing multiple keys from a dictionary safely
... extra line for existence checking personally, and it's significantly more readable unless you already know about pop(). On the other hand if you were trying to do this in a comprehension or inline lambda this trick could be a big help. I'd also say that it's important, in my opinion, to meet peop...

...
Incidentally, ((->) e) is also the reader monad--with Reader and the like just being newtype wrappers--and the ask function is then id, so that's the I combinator as well. If you look instead at Haskell Curry's original BCKW basis, B, K, and W are fmap, return...

...
@bvdb: If you want lots of flexibility, you've already screwed up by implementing a singleton in the first place. The ability to create an independent instance when you need it is rather priceless in itself.

Why doesn't C++ have a garbage collector?
...h a garbage collector in the way? Other things would be affected such as threading. Python has its global interpreter lock mostly because of it's garbage collection (see Cython). Keep it out of C / C++, thanks.
