Not implemented correctly.

This doesn't implement SIEVE correctly.

Specifically, I see no indication that...

• a record is made when a node has been visited, the core mechanism used in cache eviction.
• cache eviction ever happens

Hi @GravisZro,

Yes, this remake is not following the original proposal and does not match the Dlang implementation.
It's not ideal and I'll need to review the current implementation.

This current implementation was a response to the initial proposal below.

The Benchmark previously carried out based on the old implementation, resulting poor performance with std::unordered_map.

My suggestion is to revert to the poorly performing version that worked correctly and then modify it. Slow is always better than non-functional.
