[Perl 6] Class Attributes

John M. Dlugosz has asked for the wisdom of the Perl Monks concerning the following question:

Can someone help me figure out what the Synopses S12 means concerning "Class" attributes?

     our $.attrib;
     our $!attrib;
[download]

Are the access methods generated on the Class object or on this object? If the former, what does "inherited" mean? And on the second example above, what does it mean that the attribute is inherited, if there are no accessors?

—John

There's no "inherited attributes" in Perl 6. What you have is inherited accessors. `our $.attrib` is actually the same as... `our $!attrib; # but it keeps the original name stored for introspecti +on... method attrib { $!attrib }` [download] daniel	[reply] [d/l]

I know. So, what does "inherited" mean if there are no accessors? That's what S12 says.	[reply]

Are the access methods generated on the Class object or on this object? What difference does it make? I ask because S12 says Attributes are stored in an opaque datatype, not in a hash. Not even the class has to care how they're stored, since they're declared much like ordinary variables.	[reply]

What difference does it make? Whether you call it with `$obj.a` or `$obj.^a`.	[reply] [d/l] [select]
