My verdict would be: too little, and far too late. The damage -- significant damage -- to both language variants was done and dusted a long time since. Sad to say, but I think recovery at this stage is impossible for both camps.

In part, the marginalisation of Perl(X) has come about because different parts of its once hugely broad domain wanted different things from it.

• The web market wanted a simpler language, substituting built-ins for common patterns of code: They got PHP.

  Server side for 'simple' websites that is. For anything interactive Javascript/JQuery is really the only player in a game that Perl simply had no cards in.

• The math/science/CS people wanted less magic and more rigour: they got Python.
• The embedded market wanted smaller, cleaner, reentrant: they got Lua.
• The corporate IT world wanted "reusable code" -- despite that 95% of reusable code is never reused -- and that means objects: they got Java.

Even without the self-inflicted wounds caused by the naming, delays and infighting, Perl was always going to have a tough time to compete on all fronts. With them, it stood no chance.

Whilst I still use Perl5 for prototyping, I haven't produced a 'production program' in it for over 2 years.
