The quotes are not the problem. Windows is. The example was meant as an excercise to the reader, but that doesn't seem to work :(
perl -pi.bak -we...
will solve this specific issue, but it won't fix the way he thinks

The quotes are not the problem.
Are you sure? (It might not be the only problem, but I think at least one...)
I don't have a Windows box here to try, but IIRC, ' is not
treated as a special character by the Windows shell, so it just passes
on the single quotes as is. IOW, the Perl program would get the
string constant 's{Text::CSV}{Text::CSV_XS}g' as the code to run
(instead of the substitution command without the quotes) — which is why it rightly complains "Useless use of a constant in void context".
You'd get the same error on Unix if you had typed (of course, this doesn't work on Windows either... just to illustrate what's happening):
$ perl -pi -we"'s{Text::CSV}{Text::CSV_XS}g'" *.pl
Useless use of a constant in void context at -e line 1.
