Test dev examples

References and relevant issues

Alternative to #6763.

Description

Test dev examples to ensure they don't go out of sync.

@Czaki the failing example is related to 2d hash in labels... is it even relevant anymore? If so, could you fix it?

[Czaki]

No. We have changed the hashing mechanism. I will try to check it tomorrow.

[Czaki]

The current mechanism is totally different, so I think that whole example could be removed.

I don't liek the idea of having test-specific code in the examples... I'd rather just skip this one or refactor it ^^'

Hm. Looking to documentation, maybe we should just monkeypatch sys.argv?

A number of alterations are also made to the sys module. Firstly, sys.path may be altered as described above. sys.argv[0] is updated with the value of path_name and sys.modules[name] is updated with a temporary module object for the module being executed. All modifications to items in sys are reverted before the function returns.

What do you think of this version?

[brisvag]

Fail seems unrelated.
