You're a hair saver !! :-))
Just the insight I needed - declaring a package variable,
$template, and changing
define() to...
sub define {
my $self = shift;
my $type = shift || croak "No type name";
unless ($template) {
local $/ = undef;
$template = <DATA>;
}
my ($code, $parent, $subclass) =
($template, __PACKAGE__, __PACKAGE__ . "\::$type");
$code =~ s,##PACKAGE##,$subclass,g;
$code =~ s,##PARENT##,$parent,g;
{
my $WARNING = '';
local $SIG{__WARN__} = sub { $WARNING = "@_" };
eval $code;
croak "Failed to create subclass: $subclass - $WARNING$@" if
$WARNING || $@;
croak "Problem with subclass: $subclass - cannot new()" unless
$subclass->can(qw/new/);
}
print STDERR "Created type: $type\n";
}
... works fine.
Thanx again
At last, a user level that overstates my experience :-))
