Here's a question: Of what significance is the use of :A in this case,
as opposed to :a ? That is, why use :A at all here? Can you come up
with an example where :a and :A differ that would still be broken by
the change?

} # We know :A resolves using the same rules as directory changing,
} # so use that.
} resolved=($file(:A))
} print "\nUsing $file with :A => $resolved"
} cat $resolved
I don't want this discussion to become circular, but don't the comments
there imply that what's desired/intended is for :A to respect CHASE_*?
(That's still different from what Daniel originally suggested, because
he wants the default to act like CHASE_LINKS, but at least it's been
touched upon in the -workers side of this discussion.)
If I were going to re-design this from scratch, I think I'd aim for a
parallel with "cd -L" and "cd -P", and thus
$var:L - like current :a, never chase links
$var:P - like Daniel's :A, always chase links
$var:A - one of the above, depending on CHASE_LINKS
(and never have :a in the first place). Incidentally, outside of an
actual "cd" there's no point to examining CHASE_DOTS.
Given where we are right now, adding :P and shrugging our shoulders
about :a and :A seems the most reasonable escape hatch. Plus adding
a bit to the :A documentation, perhaps. I suppose we could also make
:L a synonym for :a just for mnemonic.
