The talon demonstration from the last link was inspiring, but it works in the exact opposite fashion that I would have imagined. The code-development examples are command-based, with a command to enter phrase mode. I'd have expected with technology such as tree-sitter and IntelliJ etc, that by parsing the syntax tree of current computer language for completions, development could occur completely in phrase mode with only a few commands for handling unknown inputs such as new variable names.

I'm curious if anyone has ever tried implementing the latter, or compared the two approaches. I'm sure there would be many obstacles I haven't considered.
