Kinda.  

To be honest, Perl does do autoderef in at least two places.

1.

    $fh = *FH;
    $fh = \*FH

can be used equivalently, because a typeglob ref is autodereffed
as need be in I/O operations.  (Not to mention *FH{IO}, even.)

2.  bless doesn't bless the reference passed, but its underlying referent,
doing an autoderef to find the referent.

and maybe

3.

    $glob = 'SYM';
    $glob = *SYM;

are equivalent.
