Dollar could not by ugly. It is a money symbol :-)
Or did you mean "$ is ugly because it looks too Perl/PHP-ish"? :-)Does "@" look more esthetically than "$"?
6. A new statement is provided to declare globals.
Declaring each used global in special global-declaration-statement is boring.
When you want to determine whether this variable is global or not, you have to search for global-declaration-statement that may be located far from the current line.
On the opposite, when you see "$var", you already know (immediately and without any efforts) that "var" is global.
So, "$var" notation results in more easily readable code.
