it's used in (which determines which variables are in scope inside the eval),
and it's easy to miss compilation errors, since eval catches them and sticks
them in $@@ instead.  This module attempts to solve these problems.  It
provides an eval_closure function, which evals a string in a clean

attribute declaration, object construction, inheritance, and maybe more.  With
Moose, you define your class declaratively, without needing to know about
blessed hashrefs, accessor methods, and so on.  You can concentrate on the
logical structure of your classes, focusing on \"what\" rather than \"how\".
A class definition with Moose reads like a list of very concise English
