I don't think Perl 6 "has" to do anything of the kind. It would
be a mistake to try.

"There's more than one sensible thing. There's more than one safe
thing."
And there is more than one open. Perl does have fopen/fdopen/freopen,
but they're accessed through other techniques besides the name of the
operator. For example, Perl spells C<fh = fdopen(5, "r")> as C<open
$fh, "<&=5"). The unique technique is there, just pushed out of the
operator name and into its parameters.
And then there's sysopen().
But open() is beside the point, no matter that it supports my point. :-)
As you know, under Unix, there's no such thing as "the current
directory" as a string. The only durable current directory is the
device and inode of C<stat('.')>. It's not wise to conflate the
current directory with a name that at some point in the past could
have been used to reach it.

Then I answer him with the same patience I answer someone who asks
how to get the filename corresponding to an open file descriptor:
"There is no portable way. Tell me what you want to do, and maybe
I can help you."
