pp.deep compiles and evaluates the expression with eval(code, frame.f_globals, frame.f_locals), but generator expressions, comprehensions, and nested lambdas inside the expression run in their own function scope where the eval frame's locals are not visible, so any reference to an enclosing-function variable raises NameError (reported as !!! NameError! in the output and re-raised, issue #75). This merges f_locals into the globals dict passed to eval so those names resolve via the eval frame's globals from any nested scope, and stops mutating the caller's f_globals for the wrapper hooks.

Closes #75
