Consider `print join '.' => unpack 'C4', 127.0.0.1` prints `127.0.0.1`.

For perl it does

Any literal that is made of numbers together with 2 or more dot is a
version string.

version string.

Well, not strictly, as 1..2 is not a version string, but I think you got
the point. There must be numbers between the points, and te points must
not be at the beginning or the end.
