Python is not Perl. By that I mean Python in general tends not to use non-alphanumeric symbols unless they already have a well established meaning (such as quote marks, arithmetic operators and so on).
Yeah, I don't think '${...}' is appearing, too. As I wrote, it was chosen for implementation reasons. I'm open for other syntax options.
I'm curious what you think about another way to construct dictionaries.
