TheBook 2.7.3 :
"In Mathematica there is a general convention that only built­in names should 
contain upper­case characters. Assuming that you follow this convention, you 
can use @ as a metacharacter to set up string patterns which match names you 
have defined, but avoid matching built­in names." 

BUT : It's a pitty that the dollar sign is defined as lower case:




*** see? I don't get myList because of capital L inside:

          "$AnimationFunction","$BatchInput", ...very-long-list...,"$UserName",

too bad !
