How To Install perl-Eval-Closure on Fedora 36
Introduction
In this tutorial we learn how to install perl-Eval-Closure on Fedora 36.
What is perl-Eval-Closure
String eval is often used for dynamic code generation. For instance, Moose uses it heavily, to generate inlined versions of accessors and constructors, which speeds code up at runtime by a significant amount. String eval is not without its issues however - it’s difficult to control the scope it’s used in (which determines which variables are in scope inside the eval), and it can be quite slow, especially if doing a large number of evals. This module attempts to solve both of those problems. It provides an eval_closure function, which evals a string in a clean environment, other than a fixed list of specified variables. It also caches the result of the eval, so that doing repeated evals of the same source, even with a different environment, will be much faster (but note that the description is part of the string to be evaled, so it must also be the same (or non-existent) if caching is to work properly).
We can use yum or dnf to install perl-Eval-Closure on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install perl-Eval-Closure.
