I've never been 100% sure whether referencing $^E, (which I always use myself), is effectively a synchronous call to GetLastError(), or whether it ($^E) only get's set if the XS code arranges to do so? Hence my reluctance to recommend $^E to others directly.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
