I did not look into it before at all, but I'm amazed by how small the actual changes in this PR are. you did quite some precondition work already before though, right?

Before the vacation I commited this #1548 which famously fixed something like 18 issues 😅

On vacation I could not stop thinking about this and during the afternoon break when kids were asleep I couldn't help myself but do something about problems the previous code uncovered.

I've been fixing various related bugs, and the CI has been finally green last two days or so 😅 This dev cycle has been challenging to say the least.

Some of the notable fixes are:

• 1537424
• 229df9b
• e06f6f0 (optimization)
• dbdcb81 (another optimization)
• ed6548c (this fixed a combinatorial explosion with SimpleXMLElement that made Prestashop integration test to run indefinitely)
• 14592dd
• 32353a9
• 46a8f32
• 6173110
• a6cec39
• 771b860
• a96cdf2
• a9a2b60
• And finally Tagged unions #1547
