An interesting feature of the visual graph programming language was that all variable and function names are optional (but useful) comments Do you perhaps remember the name of the project? This is mightily interesting. I've thought about this many times, that if you represent a program as a graph (instead of a tree) you don't really need 'names' or 'symbols' as such (except to make it understandable to humans), just connections. This allows for a cleaner separation of syntax and semantics, and would make it easier to manipulate programs without having to type.
