Fellow Monks,

Recently there was a post on array refs that had a follow-up stating you could force a list into array context using @{[ &make_list_here ]}. This isn't what i'm doing. But it relates...

A general warning, yes, i could use Parse::RecDescent, but i'm still trying to do some things the hard way to learn why other things work the way they do.

So i'm parsing a file and most of the data is flat, but there are sometimes when i want to get a hash out of the data. So the code i use is:

# this is in a loop that iterates through the file
# and at some point it runs across:
      /(\S+)\s?=?\s?\[(.+)\]$/  && do {
                                $hash{$1} = split /,/, $2;
                                next;
                                };

This works, but with warnings i got the message:
Use of implicit split to @_ is deprecated

Looking this up it says i was assigning to @_, but it doesn't look like that at all to me. That looks like assingment to a hash entry as an anonymous list. When i apply the context generating code above like so:
      /(\S+)\s?=?\s?\[(.+)\]$/  && do {
                                $hash{$1} = @{[ split /,/, $2 ]};
                                next;
                                };

the error message goes away. i'm glad the message is gone, but i'm wondering why it gave that error message (which seems inappropriate) and why this fixed it.

please enlighten this quandering quaffer of quintessential qualms (or not ; )
