Hi! Stumbled on this whilst looking through the cargo template RFCs. From the docs, it's not obvious (at least for me) whether this is supported so I figured I'd just ask as it might be a good feature addition in future:

If I have a variable of "project", can I use the input the user provides in a default for another variable?

Here's an example of why, albeit a bit of a dumb one:

Let's pretend I want to generate a *_manifest.txt file. If you name your project "my", I would generate "my_manifest.txt" unless you chose to override the name to "other_manifest.txt". So I'd be using the project variable provided as the default for the manifest variable (or whatever).

Is this currently possible?
