Compilation fails with Rust 1.72

This is caused by Rust 1.72 change Use 128 bits for TypeId hash

This is strange. I thought commit 947a73b4d87b5000a8e5719ad28efc0eea68bff1 which is included in the version 0.2.9 of the crate would have fixed that already

Ah, indeed it does. I'm trying to compile Whisperfish, which is stuck around 0.2.5, so this bug is irrelevant - and so is the merge request.
