I'm sorry, but I consider this a nonsensical pseudo-technical question.

As mentioned in my other reply, the "version" module is part of the official
Perl distribution (and thus included in the "perl" package). It can therefore
be considered official and it should be stable, and therefor so should its
output when parsing versions.

The function in my script is extremely simple. It does the following:
* checks if the passed version is defined
* checks if the passed version can be parsed by "version"
* converts the version to a pure decimal form with "numify" from version
* replaces the underscore (representing an alpha version) with "a" (see
  Pacman's documentation if you do not know how it treats letters in versions)
* inserts a decimal point between the major and minor version numbers, which
  formats all versions to x.xxx or x.xxx.xxx

The last two steps are the only extras. Everything else is within the "version"

The replacement of "_" with "a" follows directly from the meaning of "_" on
CPAN and the way Pacman handles letters in versions as alpha releases.

The final step provides a standardized package version that Pacman can
understand and which is the most human-readable.

Both of the final steps are simple linear transformations. Where exactly would
you like to see unit tests for this script?
