I disagree. Consider the code:

#!/usr/bin/perl
$foo = "this is a \\ test";
print "Foo: ($foo)\n";
($bar) = $foo =~ /([\-])/;
print "Bar: ($bar)\n";

By your reasoning $bar should be '\'. It isn't. This script prints
Foo: (this is a \ test)
Bar: ()

Change $foo to "this is a \\ test - " and $bar becomes '-', not '\'. The \ before the - in the character class [\w\-] isn't escaping anything, true. But it doesn't get added to the character class.
