Hi, I have a tree datastructure where mutating some nodes *may *trigger a mutation on some other tree nodes.
This tree should be accessible by multiple goroutines but mutated by only one at a time. As such, I wanted to have a global lock on the tree such that mutatiing node methods should acquire this lock beforehand. But it seems to require for the mutex to be reentrant? I have tried to create a very simplified*** model to illustrate https://go.dev/play/p/v37cbYQ1jSY (***) I know people might want to suggest for the Set method to use a lockless variant when iterating over the linked nodes but in the real code, it iterates over user created callbacks instead and I don't think I can expect callbacks writers to juggle between the two kind of methods to avoid deadlocks.
