Homepage: https://metacpan.org/release/Eval-Closure
Description-en: Perl module to safely and cleanly create closures via string eval
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.
.
Eval::Closure 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).
