Why that last phrase about "considered unreachable"? If
"AssertError is thrown
or execution is terminated" it implies that execution will not
continue after
assert(0).
Yeah, you're right.
Another possibility would be "assert(0) never returns". This
assumes that throwing an exception is not "returning", which is
reasonable, since control flow does not leave via return
statement.
