food for thought - swift 5 released - bottom types, string interpolation, and stuff.

I would think that having an isOdd() is… odd. It seems so trivial
and short that I would suspect something different.

I understand. I did not mean to suggest you to start a new
project. I am already grateful for the contributions you made to
dlang, thank you.

I see. I was not arguing for the minimum set by removing
reciprocal functions though. What would be your criteria for
