@Laruence Sorry for the delay; they're keeping me busy up here!
Yeah I have no objection. It really sucks but I have to agree. Since it's
fixed in 5.4, it really wouldn't be worth tearing into 5.3's guts just to
correct this.
I'll go ahead and mark it "won't fix" for ya (as I try to think happy
thoughts). =)

I'd like mark this as won't fix for 5.3, fixing this will be a big work IMO,
maybe
introduce new issues, and 5.3 is quite stable version now.

Woops, drop the word "ternary" from the description/title. =)

Oh and here's the test case:
--TEST--
Test for existence of ternary isset() bug in nested arrays.
--DESCRIPTION--

Ahh ok. Is this a won't fix then since it's not in 5.4? Or is this still
something we'd want to correct?
Thanks!
