The entire thing that makes perl great is that you can write baby perl,
simple online statements like in sed or grep that do things that are
useful. That is the macro system to the extreme.....
these programs can grow up into big programs over time. given the java
example, and macros, it is like saying that you select an default class
to derive from, a default method to implement and an default object to
call print on. These defaults would be great for writing even oneliner

I also agree with you. I am aggreement in general with what is being
discussed on this thread. What makes me different is that I think that
we can migrate exisiting programs into this new framework, by modifing
them with an interface into tunes.

Yes, this is what is missing almost completly in perl. the only
interface that I can think of is the TIE interface that allows you to
interface to hashes, array and scalars. and the DBD/DBI interface that
lets you talk to databases.
