Named parameters in perl lingo are something like

 tst(-named=> parameter)

I'm experimenting with functional programming and manipulating closures.

(Update: But if you call $a and $b in sort {} "named parameters", then yes.)

I'm reluctant to deepen this discussion, many people here have a more emotional attitude about the "right way to do it".

(this results normally in useless flames where I won't/can't compete)

sic!

my $saved = $magical;

Yes I'm trying to prevent possible conflicts and having a more fault-tolerant design,thats why I'm forbidding tied vars.

UPDATE: BTW pos can be handled! 

sub dont_mess_pos { 
  my $vr=\$_[0]; 
  my $pos=pos($$vr); 
  my $s=$$vr; 
  $_[0]=42; 
  $$vr=$s;
  pos($$vr)=$pos 
}

  DB<80> my $a="xxx";scalar ($a=~/x/g);print pos($a); tst $a; print $a
+,pos($a)
1xxx1
