|Subject:||first_release behavior undefined, confusing|
The behavior of first_release is undefined. What constitutes the "first" release? Is it by date or by version? I figured it would be by version, turns out its by date. This bit me in the ass as I often use "corelist My::Module" to determine when it was put into the core so I can set INSTALLDIRS appropriately. This bit me in the ass as Test-Simple is in 5.6.2 and 5.7.3 but as 5.7.3 was released before 5.6.2 then corelist reports 5.7.3. The result is ticket 25163. I think sorting by version is more useful, its the order most people think of. A progression of newer technologies. Most folks are unaware that 5.7.3 was released after 5.6.2. The versions which sort differently by date and by release are: 5.4.5 5.9.0 5.6.2 5.5.4 5.9.1 5.9.2 5.9.3 At the very least it should be documented. Adding a first_version() method would neatly solve the problem though then the question of which to use for "corelist" arises.
