For more than a week I am now trying to get a patch right that will fix the GLOB to LVALUE assignment bug that tormented
Perl5 ever since. My initial attempt only addressed a problem relating to tied elements and I learnt from Dave Mitchell that the problem was more general.
However, Yitzchak spotted a small omission in my patch and suggested to rearrange the Perl types. This old saying that it takes 10% of the time to solve 90% of the task and 90% to fix the remaining 10% is obviously very true.
