Re^3: Problems with a regex?

To /^\Q$stack\E$/ (emphasis on the \E).

Why? If the \E comes at the end of the regex it is completely redundant. A pointless, useless addition.

In the absence of evidence, opinion is indistinguishable from prejudice.

I would think so too, reading the docs. But with `/^\Q$stack\E$/`, I get: `Service name: "MY NEW SERVICE (TMP)" Popping stack: . Adding to stack: "MY NEW SERVICE (TMP)" Service name: "MY NEW SERVICE (TMP)" It's on stack, keep compiling` [download] And with `/^\Q$stack$/`, I get: `Service name: "MY NEW SERVICE (TMP)" Popping stack: . Adding to stack: "MY NEW SERVICE (TMP)" Service name: "MY NEW SERVICE (TMP)" Popping stack: "MY NEW SERVICE (TMP)". Adding to stack: "MY NEW SERVIC +E (TMP)"` [download] More simply: `$ perl -e "$x=$_='()';print/^\Q$x\E$/?YES:NO" YES $ perl -e "$x=$_='()';print/^\Q$x$/?YES:NO" NO` [download]	[reply] [d/l] [select]

Mea culpa! You're right. Escaping the $ makes the difference.
