The actual shelveset :)
Refactors and simplifies LexicalScope and allocation of local variables. Previously a LocalVariable instance was created per each local variable access, which is unnecessary. Since many scopes don't define any variables at all we allocate a variable dictionary lazily.
We also used to fallback to dynamic variable lookup in evals in some cases even though we could lookup statically.
