Safe can -- if (ab)used correctly -- prevent your program from dieing as well.

I believe that the source code to life is written in Perl :-)

    Safe can prevent die from being called, but not dying in general, or even due to "bad" derefs.

    If you wanted to change the behaviour of `->`, especially in a lexical scope, you could use an opcode checker. The autovivification pragma is an example of such.

[marto]: 1nickt, glad to hear it, I'm sure you'll bring improvements to their stack in due course ;)
[1nickt]: Just trying to adjust to a new culture. Better doc than I am used to , but quite a bit more Agiley meta-bullshit; at least half a dozen meetings a week, strict "sprint" schedule etc. I'll adjust. And I hope to just switch off after the "scrum" each day at
[1nickt]: ... the end of the afternoon. marto How are you, snowed in? Mum and Dad expecting snow today in Surrey. (Have 5" on the ground here in NJ. And my son's high school in SOCal closed until after Xmas due to fires.)
[Corion]: 1nickt: In a sense the meta-bullshit might even be beneficial to you as you get to hear the cow-orkers talk (or not talk) about the issues you perceive. I think Agile is mostly about the meta ;)
[Corion]: 1nickt: On Sunday maybe 10cm of snow fell, and the airport closed, and the trains stopped running etc :) It always comes as a surprise that snow falls here during the winter...
[marto]: 1nickt, no snow, just some ice on the roads and the usual idiocy associated with humans and driving in less than ideal conditions
