Crosscut

The combination of restricted structural editing and postfix syntax introduces a lot of friction into day-to-day editing. What could we do to address that?

• We could not have restricted structural editing, but then we'd have to deal with the problems of free-form structural editing. This seems like a bad trade-off.
• We could circumvent the problem, by having special syntax for function literals and other things. I think that's going to happen anyway at some point, but for now, it would be a distraction from more important things.
• We could find innovative solutions to those problems. But that would take a lot of effort that I couldn't spend elsewhere, for uncertain gain.

Switching to prefix syntax avoids this problem, and others. I think that's simply the best solution right now.
