[ID 20010305.013] do &function -- unexpected behavior

This is a bug report for perl from japhy@pobox.com,
generated with the help of perlbug 1.28 running under perl v5.6.0.

jeffp@hut [1:00am] ~ #102> perl -w
sub foo { print "ok\n"; 123 }
do &foo;
ok
Perl v123.0.0 required--this is only v5.6.0, stopped (did you mean
v123.0.0?) at - line 2.


I do NOT know what to make of that.  It seems like Perl interprets the
return value of a 'do &foo' as something to send to 'use' for a version
number.  But what do you make of:

jeffp@hut [1:02am] ~ #105> perl -w
sub foo { print 1 }
do &foo;
Perl v49.0.679940 required--this is only v5.6.0, stopped at - line 2.
1


That is bizarre.
