- Remove a double layer of string eval that was introduced in 0.07 as an
intermediate step in figuring out the unique package thing - it's not
necessary with the final implementation, and just makes things slower
and hides errors.
- the given source is now evaled in a unique package for every
eval_closure call (it used to always be evaled in the Eval::Closure
package, which was especially buggy). this is to avoid issues where one
eval_closure modifies the global environment (by, say, importing a
function), which could mess up a later call. unfortunately, this means
that the memoization stuff no longer works, since it will result in
memoized results using the original package, which defeats the purpose.
i'm open to suggestions on how to safely reenable it though.
- clean up a few stray lexicals we were still closing over in the 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.
|
|
|
|
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).
