Re^3: Why are list items passed to die() combined into a string?

Thing to note: neither $" or $, will impact the concatenation seen by $SIG{__DIE__}(e.g. join '', @_). This contrasts print, where print "@_" or print @_ can have their behavior impacted.

I far prefer overriding die to working with $SIG{__DIE__} myself, since the latter's behavior isn't what I usually actually want to impact.

Ah, good point. Overriding functions will be my next project. I had considered using `"@_"` to pass to my email routine just to let my future self know it needs to be a single string. But since `@_` has already been concatenated that doesn't make sense. Now I'm thinking passing `$_[0]` might be better.	[reply] [d/l] [select]
