Description
ROOT's interfaces are mature - they have served us well for decades! But current C++ is different, and has properties that we need:
* ownership becomes type-safety
* concerns are decomposed, reducing interface clutter
* C++'s standard collections are ubiquitous and performant
* optimizers are at a different level than even 5 years ago (let alone 20)
* current students learn different syntax than students of 10 years ago
While we see the need to react, we do not see a backward compatible path into this future. This presentation will show what ROOT's future interfaces might look like, as the basis for a discussion. It will also present how we plan the migration to these new interfaces. Interfaces that will be covered or at least sketched are
* histograms, showing the benefits of an interface with current C++
* smart pointers resembling ROOT's ownership behavior
* TCanvas interplay as an example for ownership management
The goals are an increase in clarity and simplicity, a reduction of memory issues, and an increase in speed. Come judge!
