A more practical application would be: my $foo; # Code which might or might not set $foo... $foo //= 23; # or $foo is default(23); In such a case, the C<is default> just looks plain odd to me. Properties are meant to be out-of-band information; miko's suggestion would have this property setting the *value* of the variable. Weird. C<//=> seems perfectly reasonable to me. Trey
