A repository where I'll put experiments learning, proving or disproving things about C++. These experiments will feature measurements, use Tracy to show behavior, and generally have the goal of simplifying normal C++ usage.

Initial commit of a small project to keep a record of various things in C++ that confuses me, other people, or are just down right dumb and should be avoided. This will be where I link people who tell me something is fast or better.

Added a small micro example of the problem with SFML's use of const on drawable virtual functions which shows the _real_ reason they did this is because of a poor design decision to make both Drawable and RenderTarget equally in charge of drawing the other. AKA the 'Deadly Embrace' design flaw.

Original should be the name of the starting point for this experiment.

The fix is simple: Just don't have RenderTarget (which is literally named render TARGET) also be in charge of rendering things to itself.

Two possible ways to fix drawable to avoid the const problem, but not quite right.
