That's wrong, the variable is still in the symbol table, it's value is just undef.
Do not shoot the piano player, ... :-)

In FAT if you delete a file from the directory it is still present but marked as deleted.

So the fact that it is still present does not change the fact that semantically it is deleted.

In other words, if the item in a Perl symbol table has value undef for all practical purposes is it that same as deleted item in FAT and should be treated by interpreter developers in the same way as "not found" item.
