Re: $| pre and post increment and deincrement behavior

If you want $| to be 1, assign 1 to it. Pre- or post indcrement is unnecessarily "clever" and could bite you if $| doesn't happen to have the value you assume.

Someone seems intent on repeating this particular piece of misinformation, so perhaps it's worth repeating (just this once) that it's incorrect. I do agree that `$\|++` is unnecessarily clever, since it might confuse an ignorant maintenenance programmer, and that `$\| = 1` is clearer. But it's simply wrong to say that it could “bite you if $\| doesn't happen to have the value you assume”. It couldn't, for reasons that will be obvious to anyone who has understood this thread.
