To set $! to a constant 1, you need to give the typeglob a reference to it:

What I meant was not to assign the constant 1 to $!, but to make $! an alias for $1, which is read only too: 

*! = 1; "text" =~ /.(..)/; print "$!\n";
__END__

It's notable that the typeglob assignment to constant destroys $!'s dual value magic:
$ perl -e'$! = 1; print "$!\n"'

I don't get this. There's no typeglob assignment in your example. Maybe a typo? If you meant *! = 2 then you'll get an alias for $2, as expected. So no $! magic. (Thank you anyway for remembering me that there's a CUFP I wanted to share :)).
