perl-Eval-Closure - Safely and cleanly create closures via string eval
- Description:
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.
