Because destruction/disconnection related bugs can be hard to find

What is your opinion of DBIx::Connector? Do you think you should delegate the complexity of keeping database connections alive to it?

Also, please note well that destruction bugs and disconnection bugs are two separate classes of problem. I dont know which the use of double quotes about $db was supposed to address. But I do know that common sense about reference counting between a DBIx::Simple database handle and DBIx::Simple::Statement which has-a database handle should not require any particular weakening like you are doing. Just think for a second:

  1. we create a database connection, D
  2. we create a statement instance, S, which refers to D. This makes the reference count for D== 2
  3. we create a another statement instance, S2, which also refers to D. This makes the reference count for D== 3
  4. S2 goes out of scope. Reference count for D drops to 2
  5. S goes out of scope. Reference count for D drops to 1
  6. D goes out of scope, reference count for D drops to 0 and D is extinguished
I simply dont understand why we need to prevent the reference count from naturally increasing and decreasing as the DBIx::Simple instance becomes a compononent of DBIx::Simple::Statement instances.

The trick for wrappers like metaperl's Local::DBIx::Simple could be to somehow keep a reference around and do some of their own lifecycle management.

Without any concrete suggestions for modification, I dont know what to say or try. But I would say this. Local::DBIx::Simple is a very simple, clearly written wrapper and it isnt working.
