Re^3: Problem with Perl editors.

Are you sure?

perl -e "$| = -1; print $|"
[download]

$| is magical in that it can only have the values 1 and 0. $|++ switches unbuffering on, while $|-- toggles from on to off and back to on.

Hm, this works on my current Perl installation, but I remember running into the problem as I explained it. Odd; I wonder if it was an old Perl, or something custom on that system... Larry Wall is Yoda: there is no `try{}` The Code that can be seen is not the true Code	[reply]

I echo radiantmatrix's comment: better to explicitly say what you mean. Where alternate 1 does the job, but offers no significant performance advantage, is not significantly shorter and is obscure (to any degree), then alternate 2 which is explicit is always better (unless of course you are writing deliberatly obscure code). Perl is Huffman encoded by design.	[reply]
