Thanks for the in depth answer. Very helpful. You've helped fill
some tragic holes in my basic knowledge of perl. I've learned the
little I know... by hook or by crook, not a systematic progress from
basic to higher skills.
About just using 'shift': How I happened to be using that weird
looking notation at all was because I thought it was a way to avoid
the extra step of compiling the rgx in qr// after shifting.
I did try that long ago but found that 'shift' is not interpreted
properly inside qr/shift/.
I guess that may be a pretty lame reason, and better to just include
the extra couple lines.
Or do you mean there is a way to use just 'shift' inside qr//.
Maybe with some tricky quoting?
If used in the current example, the notation above just skips shifting
at all and passes the rgx to -d
