> on unthreaded, once.

I tried your code on "unthreaded" perl and it prints twice.

It seems like this weird "interpolation" ° resolves to "x1" =~ /x1/ which doesn't make much sense as a bug demo.

I don't understand how this is proving anything???

  DB<1> say "${\1}"
1

you probably meant a the regex back-reference to the first match \1 ? But there is no first match ... ehm???
