Oh, I agree the davido's replies are mindbogglingly helpful! I often find myself pointing directly to one of his replies because, despite my anal retentiveness and nit-picking OCD tendencies, I simply cannot find any improvements, or caveats, or gotchas ... at all. Two recent examples spring to mind:

• Re: What do I use to release a module to CPAN for the first time? by davido (pointed to from Writing Solid CPAN Modules)
• Re^2: Unable to Understand grep and hash use for prime no. by davido (found while reflexively creating yet another list)
