I need to do a hash some kind like this:
Member => {email => Email, name => Name, lastname => Lastname}

But I get a hash in foreach loop so I need to append a hash to hashes.
e.g.
First round: Member => {email => Email}
Second round: Member => {email => Email, name => Name}
Third round: Member => {email => Email, name => Name, lastname =>
Lastname}

Can I do that and how?
In my case I cannot do the array because I need to use this hash to
generate yaml later.
If I do as the array, the formatting what I get in yaml is not what I
need.
Pls help...
