i think it may better stay so. It's definately not very annoying since anyone sane wouldn't write that. You could just as well write (x+b) :> -eye

Nonsense. It's non-standard behaviour, and in such a simple thing that any other compiler handles correctly. I really don't think you'll convince Walter to *not* do this, given his desire to be fully-conformant. And as for your assertion that no-one would use such a construct, I'll just smile, and you can wait until you've read "Imperfect C++". Now you've got three reasons to buy it (the other ones being the Properties chapter, and my mentioning your request for properties in the acknowledgements). :)

It's probably so to guard for bugs.And as for your assertion that no-one would use such a construct, I'll just smile, and you can wait until you've read "Imperfect C++".

I really don't need to count the reasons, i know i want to get it as soon as it's out. :> Unfortunately, /me would not be able to raise your sales much only by bying it myself. -eye

Don't be so sure. You might account for up to 50% of sales! (I know my mum's going to buy one <g>)

I've been spreading Word, so i'm sure i account for at most 34% of sales. -eye

He usually posts a response on the NG. Did you try all the cases? I just tried with 8.40.1, and it still fails. "KTC" <me here.com> wrote in message news:c18pf7$30pl$1 digitaldaemon.com..."Matthew" wrote...All compiles except where marked. All should compile

I've just copied and paste exactly what you posted in the orginial post and it compiles fine for me... scppn.exe gives version 8.40.2n KTC -- Experience is a good school but the fees are high. - Heinrich Heine

That's what I have. I must conclude that I pasted an incomplete version. Including here again ... Walter, I presume this'll be easy-ish to fix. Any ETA? :)

Ahha, discovered why. It compiles if one compiles it as C++ but not if it's C.

That's interesting. It also explains a few things I was wondering about. :)
