tfpt review "/shelveset:LexicalScope2;REDMOND\tomat" Refactors and simplifies LexicalScope and allocation of local variables. Previously a LocalVariable instance was created per each local variable access, which is unnecessary. Also, since many scopes don''t define any variables at all we allocate a variable dictionary lazily. In evals, we used to fallback to dynamic variable lookup in some cases even though we could lookup statically. Tomas
