Ada++ makes two changes to the Ada language. First, it changes some keywords into new keywords or symbols, but in a gross way (the case example, is becomes : as a blanket rule, even when it leads to : being paired with }). This could be done by a (tedious) awk program or sed script. The second change it makes is that use will also with a package, that's a nice ergonomic feature. But it's the only thing of modest complexity that it does to change the language. There are no other enhancements to the language that it introduces that make it a compelling thing or an obvious non-joke (it's release date for 0.2.0 was 1 April 2021).

The actual Ada developers are focused on actual language enhancements with the Ada 2022 standard and increasing the scope of properties that SPARK (a proper subset of Ada now) can prove about a program. Including approaching some of the properties that people find desirable with Rust's borrow checker and lifetime analysis. Ada++ should be doing things like that, meaningfully improving the language and not just being a glorified awk program that doesn't change or add any real syntactic or semantic properties of the language. Also, the author should stop doing releases on April Fool's Day if they really want to be taken seriously.
