$, = ','; # I like to print out array items this way

@my_array = ('Angel','Buffy','Cordelia');

#     Now I have an array with three items. I want
#     to make it be a value in a hash.

$my_hash{'my_key'} = [@my_array];

#     Turns out to be the correct way to put an array into 
#     a hash value.

#     But why? Why not 
#         ($my_hash{'my_key'}) = @my_array;
#     for instance? That was my first thought, array context
#     on the left hand side comes from brackets -- or
#         $my_hash{'my_key'} = \@my_array;
#     is something else that occurred to me that didn't work.

#     Now I want to push something onto the end of the
#     array in the value:

push (@{$my_hash{'my_key'}},'Darla');

#     is the right way to do it, but first I tried just
#     a regular push, like:
#         push ($my_hash{'my_key'},'Darla');
#     after all, Perl "knows" that value is an array,
#     but this doesn't work! It tells me "Type of 
#     arg 1 to push must be array (not hash elem)"!


#     Now I want to get my array back out again, I have to
#     do this:

print @{$my_hash{'my_key'}};

#     in order to make it come out as an array and
#     not as "ARRAY(0x35fd724)". But why?
