Hi, As much as I like writing new code in 5.14 (the use re '/xms' pragma really bought me), I must agree with some of the things said here.
When you have tens of thousands lines of old code (global vars all around, using ancient bugs, and works by magic because too many people have hacked too many edge cases), it's extremely frightening to upgrade. Most of the organizations I work with still use 5.8.x. For new code (and when possible), we install perlbrew and run the new code in a new environment, but since most old code has no testing, running it under newer versions may or may not work, and the failure may not even be visible. On an ideal world, all code would have unit testing, and no one will ever be afraid to upgrade :) On 19 May 2011 15:17, Eli Billauer <[email protected]> wrote: > Gabor Szabo wrote: > > > Wow, no one has anything to say? > > > > > In a way, a no-answer is an answer. > > What I find interesting, is that on one hand, everyone seems to agree > that upgrading should be done constantly and continuously and that > running end-of-life software is like making love with a corpse or > something.
