Hello,

I have a class A which inherits from a NonMoose class. Therefor I use FOREIGNBUILDARGS to set the default for the nonMoose class constructor argument:

package ClassA;
use Moose;
use MooseX::NonMoose;
extends 'aNonMooseClass';

has 'param2' => ( isa=>'Str', default=>'Default param2 in class A' );

sub FOREIGNBUILDARGS {
    my $class  = shift;
    my %args   = @_;
    my $param1 = exists $args{param1} ? $args{param1} : 'Default param
+1 in class A';

    return ( $param1 );
}

Now I have a regular Moose class B which inherits from class A.

param1 is to be fixed to 'PARAM1-CLASSB' and param2 is to be fixed to 'PARAM2-CLASSB' for all instances. So, I figured this declaration:

package ClassB;
use Moose;
extends 'ClassA';

around FOREIGNBUILDARGS => sub {
    my $orig = shift;
    my $class = shift;
    return $class->$orig(param1=>'PARAM1-CLASSB',@_);
};

around BUILDARGS  => sub {
    my $orig = shift;
    my $class = shift;
    return $class->$orig(param2=>'PARAM2-CLASSB', @_);
};

As ClassB is based on ClassA I'd prefer to have a uniform way of setting param1 and param2 in ClassB. I don't bother in making ClassA more complex, but I want ClassB to be as user-friendly as possible. Can this be achieved ?

Thanks!
