Well, isn't \w also locale aware?
Example: (Germany)

% perl -e 'use locale; $_=q{äöü}; print qq{Locale aware!\n} if /^\w+$/
+;'

[download]

Results in:
Locale aware!

Thus, \w is bad when you really mean /[A-Za-z0-9]/. On the other hand, using the latter character class instead of \w is usually more of a problem for most applications. The best example is, I daresay, entering my last name in some form on the web that does this: Müller ;-)
