-slw ?

On a tangent, your shebang line draws my attention. I remember -w from the distant past. I looked up -s and it parses switches, but this code doesn't use any. So, is this just something you always use for quick test scripts? I also read about -l but don't see what it would be used for. (And does it notice that the following character is not an octnum so it gangs the -w switch and leaves the argument blank?)

`-l` sets `$\`, used by `print`.	[reply]

So it makes `print` act like `say`?	[reply] [d/l] [select]

So it makes print act like say? Yes. I (perhaps not originally so) requested a say be backported to P5. I even implemented it and sent patches to p5p but they were rejected for various spurious reasons. I used -l as a substitute in the interim, but it took such a long time that -l had become a habit by the time say became available. When I moved to 5.10, I did try to break the habit of -l, but you have to add `use feature qw[ say ];` or `use 5.010;` to the top of every script,and that is harder than -l, so I pretty much gave up on say. On the rare occasions I want to print without a newline, I use printf instead. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
