Hello Monks,

It's been a while since I last coded anything (a loooong while, I'm afraid) and it would appear that I need a bit of help to make my coding-starved brain process even the most basic of problems. Here we go...

I've got a subroutine that processes a number of items in a list. The items are all names of hashes. For example:

foreach (qw/hasha hashb hashc/) {
@keys = keys %$_;
print "There are @keys here";
}

But this attempt doesn't work and results in 

Can't use string ("%Blog::Entry::") as a HASH ref while "strict refs" 
+in use at ./blog.pl line 18.

Would someone please explain to me a) why this is and b) how I might go about accomplishing this better?

Thank you!
