Update:I'm fully conversant with how closures work at the perl level. I am interested in the details of the internal implementation. I don't know how to make this question clearer?

I'm looking to understand the internal details of how Perl implements closures. Are there any documents, blogs or other articles that explain the internal implementation?

Specifically, I'm interested in understanding the mechanism that allows a coderef to 'remember' the (location of) the variables it closes over?

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
