It in fact refers to the elsif at line 386
    } elsif ($text =~ s/^(\p{Unicode::EastAsianWidth::InFullwidth})//) {

I have read a bit the perl 5.8.0 doc I found on the web, and \p is
present.  Also I looked a bit more at Unicode::EastAsianWidth and 
I checked that the 2003 version do not look functionally different from
the version we use.

So, I have basically no clue.  5.8 is now at 5.8.9, so maybe this is 
simply a bug?  Maybe you could try to remove the
Unicode::EastAsianWidth:: prefix and see if it still errors out?
It works in my tests -- one could even consider that it is better style.
