I was thinking about this last night and came up with "parent" myself. "isa"
is too tied to the underlying details.
As for the details...
* The $VERSION thing, I'm not even sure why base.pm does it. It goes.
* Anything to do with fields goes.
* The attempts to work around global $SIG{__DIE__} goes.
* The ability to inherit from a non-file superclass is a nice feature.
I'm going to dig my heels in on one thing: import. Whether or not
superclasses should export is one thing, but how many times do you want it? 1
in 100? 1000? 10000? Its pretty damn low and there's a perfectly sensible
work around:
use parent 'Foo';
use Foo;
Getting the syntax right for importing from the parent *and* supporting
arguments *and* supporting MI will rapidly get messy, consume 90% of the
complexity, add bugs and mess up an otherwise squeaky clean interface.
I think I'm going to write this right now.
