Any reason why scala does not explicitly support dependent types?
...ce, however, in Scala we wouldn't start by encoding Sigma and Pi types and then proceeding from there as we would in Agda or Idris. Instead we would use path-dependent types, singleton types and implicits directly. You can find numerous examples of how this plays out in shapeless: sized types, exten...
'const string' vs. 'static readonly string' in C#
...compile-time.

Using i and j as variables in Matlab
...way to write sqrt(-1), and that as such there is no need to avoid using i. Then again, as Dennis pointed out (https://stackoverflow.com/a/14893729/1967396), it can be hard to see the difference between 1i and ii. My suggestion: use 1j as the imaginary constant where possible. It's the same trick tha...
