Note the trailing comma.

Which is horribly like some Python I've had to write. I hate it when syntax DWIMs the wrong way.

> python
>>> x = (1)
>>> x
1
>>> x = (1,)
>>> x
(1,)

So (1) is not a tuple, but (1,) is?

Back to Perl...

Does the number of trailing commas affect anything? E.g., [[["hello"],,,,],,,,]. (Because in Python it's a syntax error!)
