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.
