This makes expansion behaviour inheritable by placing it into the area and passing it down during layouting instead of computing some approximation of what we want during execution.
- Only add line spacing between lines. Previously, line spacing was added below
every line, making `#box[word]` higher than just `word`.
- Compute box height of text as `ascender - descender` so that the full word is
contained in the box.
The name run was a relict of the time where a line consisted of a set of runs with same alignment. While these runs still exist conceptually, they are all stored flatly together in what was now renamed from `run` to `line`.
Supports:
- Closure syntax: `(x, y) => z`
- Shorthand for a single argument: `x => y`
- Function syntax: `let f(x) = y`
- Capturing of variables from the environment
- Error messages for too few / many passed arguments
Does not support:
- Named arguments
- Variadic arguments with `..`
This extension enables you to
- quickly open the actual and reference output for a test case to the side
- re-run the test with the click of a button
- approve the test output (moves output to reference folder and optimizes with oxipng)
- Better trimming (only trim at the end if necessary)
- Fixed block-level layouting
- Improved pretty printing
- Flip inline variable to block
- Flip inline variable to display for math formulas
