Is it preferable for CODE to execute in its own namespace (the above
being a literal translation of the given code), or for it to execute in
the originally defined namespace?
Deferring to Greg Ewing for a moment [1]:
They should be lexically scoped, not dynamically scoped.
Wrapped blocks in an old namespace, I believe, is the way to go,
especially for things like...
@synchronize(fooLock):
a = foo.method()
I cannot come up with any code for which CODE executing in its own
namespace makes sense. Can anyone else?
