Would you mind adding 5.3 and 5.4 support as well? I love this library and am going to be using it in most likely a few projects -- this has...

Yeah, I get that, sometimes I struggle with motivation to work on things lol.

The STL contains algorithms for this ([set_difference](https://en.cppreference.com/w/cpp/algorithm/set_difference), [set_intersection](https://en.cppreference.com/w/cpp/algorithm/set_intersection), [set_symmetric_difference](https://en.cppreference.com/w/cpp/algorithm/set_symmetric_difference), and [set_union](https://en.cppreference.com/w/cpp/algorithm/set_union)). I don't know what algorithm implementations use, though.

In general, C++17 should be fully supported by all the mainstream compilers; its C++20 that isn't even close to being fully supported. It shouldn't be a problem.

As for avoiding multithreading problems like this, I think that, as an amendment to the comment made by @biscuitWizard above, it might also be pertinent to note ways of avoiding...

@etcimon I know, Botan is definitely a good library and I imagine that D could only add to it. Are there any plans to synchronize with Botan 3?

I ask particularly since Botan 3 has TLS 1.3 support, among [a variety of other changes](https://botan.randombit.net/news.html).

Wouldn't the MPL conflict with the MIT license? The MIT license is extremely permissive, whereas the MPL is not. And the MIT license is not on the list of secondary...

@rossberg Looking at the output example in #1494, whatever Python does makes reading the grammar perfectly fine. I attempted to use the accessibility features, but that introduced even more noise;...

As a possible alternative, have you looked at how the UEFI forum does it with ACPI machine language? (You can find that grammar [here](https://uefi.org/specs/ACPI/6.5/19_ASL_Reference.html) for ASL, and [here](https://uefi.org/specs/ACPI/6.5/20_AML_Specification.html) for AML.)...
