Just a note,
\(1, 2, 3) was a good try, but it's actually interpreted as
(\1, \2, \3). From
perldoc perlref:
Taking a reference to an enumerated list is not the same as using
square brackets--instead it's the same as creating a list of
references!
@list = (\$a, \@b, \%c);
@list = \($a, @b, %c); # same thing!
As a special case, `\(@foo)' returns a list of references to the
contents of `@foo', not a reference to `@foo' itself. Likewise for
`%foo', except that the key references are to copies (since the keys
are just strings rather than full-fledged scalars).
So, as the previous posters mentioned, the solution is to use [1, 2, 3] instead of \(1, 2, 3).
