Re: [git/perl] unusual syntax?

sub _close_hash_and_insert_object {
	my ($self) = @_;

	return unless defined($self->{hash_object_pid});

	my @vars = map { 'hash_object_' . $_ } qw(pid in out ctx);

	command_close_bidi_pipe($self->{@vars});
	delete $self->{@vars};
}
$self->{@vars} evaluates to undef. i can't find any mention of using
arrays to dereference objects in the manual and elsewhere; is this a
mistake?

This is a hash slice notation, returning an array of hash values  
matching the corresponding keys.  5.10 removed some syntax warts in  
the case of hash slices; this is more portably expressed as @{$self} 
{@vars}; this should work in 5.10 and earlier versions, and so is the  
preferred syntax.
