* Variable properties: A variable can have properties now. I have a couple in mind that will be used by the Forms framework, for example a preferred unit for display.


So it will automatically try to convert to that unit? Nice. What other properties do you have in mind?

Quote:* An event framework to trigger something when a variable changes, which will help build applications more easily. The idea is that you create a variables, 'A', 'B', for example, and define a program that does for example C=A+B, triggered every time A or B change.

Then that idea mutated into automatic evaluation of a tree of those triggers.
Now you define 'A' with a value, 'B' with a value, and 'C' with the formula 'A+B', and the system will automatically recalculate C every time A or B change.


Hmm. So this will be an automatic feature of all variables? I have mixed feelings about that, depending on how it works.

Like, say C is 'A+B', and I store 1 in A and 2 in B. If I put C on the stack, what do I get, 'A+B' or 3? If the former, how is that different from now? If the latter, how do I edit C to be 'A-B'?
