Ok, Perl 5.8.0 introduces runtime application of variable attributes.
All fine and dandy. However, I'd like to be able to pass variables in my
attribute declarations. For example:
my $bar = 3;
my Cat $foo : Legs($bar);
As perldelta (perl58delta for bleaders) says:
In particular, however, this allows variable attributes to
be useful for "tie" interfaces, which was a deficiency of earlier
So, how does one actually evaluate the $bar?
MODIFY_SCALAR_ATTRIBUTES gets called with a string
"Legs($bar)" and no hook into the appropriate namespace.
