When you use the @ sign before a users name the system should make it into a hyperlink (making it clickable and blue)... You will notice that even your @and in your question did just that even though it is not a users name yet.
This is also a bad idea because it conflates the program-addressable namespace and the user-addressable one. That's faster, cleaner, and safer than the previous approach. Of course, you don't need to use a dollar sign.
Another reason that folks sometimes think they want a variable to contain the name of a variable is that they don't know how to build proper data structures using hashes. For example, let's say they wanted two hashes in their program: %fred and %barney, and that they wanted to use another scalar variable to refer to those by name. This is still a symbolic reference, and is still saddled with the problems enumerated above.
And just use a multilevel hash to start with.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
