> The C# standard lib (often called the base class library or BCL) has seen a ton of Span<T>/Memory<T>/stackalloc internal usage adoption in .NET 6+, with each release adding more of them. Things like File IO and serialization/deserialization particularly see a lot of notable performance improvements just from upgrading each .NET version. .NET10 is faster than .NET9 with a lot of the same code, and so forth.

I worded my reply poorly, mostly in that I meant 'If Oberon has it's own stdlib, is it doing the modern performant practice' ?
