Dear Monks

I've this array that I need to copy to a hash, like:
%b = map{ $_, 1 } @a ;

[download]
This works great. But now I first delete an element from @a. The result is that I endup with and hash with one key == undef. How do I change this expression so undef values are ignored by map ??

Thanks in advance
Luca
