No. Doing:

is the same as:
($foo) = $_ =~ /pattern/;
What he's doing is getting the ()'d part of the regex, and storing i

If the standard rename() function isn't good enough, File::Copy also has a

To get that to work, you'd need to backslash the quoting character:
"he said \"hi\" to me"
qq/he said \/hi\/ to me/
but that should be a sign that you should've chosen a different character.
Using qq(), qq[], qq{}, or qq<> allows you to nest the quotes
it for EVERYTHING unless you recompile Perl. You can do it
for yourself all the time by setting the PERL5LIB environment variable to
a colon-separated list of directories to add to @INC automatically.

been exited already. (Mnemonic: like \digits.)
These variables are all read-only.
Example:
if ($line =~ /^(\w+)\s*=\s*(.*)/) {
print "setting '$1' to '$2'\n";

that holds references to $foo, @foo, %foo, and &foo (and a bit more).

- and a typeglob can be dereferenced to anything...
- then ${ $SymbolTable::{$name} } is like...

if (exists $valid_x{$x}) {
# ...
