When reading perldoc perlunicode, I've stumbled over possibility to define my own character properties for matching. I decided to try this out as an interesting alternative to using ranges.

So here's the text from the pod.

Something to include, prefixed by "+": a built-in character property (prefixed by "utf8::") or a user-defined character property, to represent all the characters in that property; two hexadecimal code points for a range; or a single hexadecimal code point.

I've created the following test script 

my $tst = "split-word another:one";

$tst =~ s/\p{IsSplitWord}+/**/g;
print $tst,"\n";

sub IsMySep
{
    return <<EOQ;
002D
003A
002F
EOQ
}

sub IsSplitWord
{
    return <<EOQ;
0041\t005A
0061\t007A
+IsMySep
EOQ
}

The execution of it gives the error 
SWASHNEW didn't return an HV ref at ./tester.pl line 3
What am I doing wrong?
