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

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)"

More simply:

$ perl -e "$x=$_='()';print/^\Q$x\E$/?YES:NO"
YES
$ perl -e "$x=$_='()';print/^\Q$x$/?YES:NO"
NO

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

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

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

The start of some sanity?
