Issue #16235 has been updated by burdettelamar@yahoo.com (Burdette Lamar).


Method :reserve_names fails if any name is already in use:

```
def reserve_names(*names)
  @reserved = names
  @reserved.each  do |name|
    fail "Name #{name} is already in use" if ENV.include?(name)
  end
end
```

So, not a problem?

Misc #16235: ENV.assoc spec test does not test invalid name

----------------------------------------
The most important thing here is an added test for an invalid name argument to ENV.assoc, which should raise TypeError.

I've also added to spec_helper.rb:

- Methods :reserve_names and :release_names, to reserve and release names used in the test.
- Method :mock_to_str, to return a mock object that responds to :to_str.

The updated assoc_spec.rb uses all of these, as will many other spec tests for ENV, as I get to them.

It's known that some of the ENV spec tests do not test a method's return value, and that some do not test error conditions (as above), so more to come.  All in good time.
