- Use a recursive descent parser so that it's easy to extend.
- Add `@args` to enable customizing command-line arguments
- Add `@should-start` to enable `nix repl` tests that error before
entering the REPL
- Make sure to read all stdout output before comparing. This catches
some extra output we were tossing out before!

@args --debugger
|
|
we enter a debugger via builtins.break in the input file.
|
|
|
|
info: breakpoint reached
|
|
|
|
causing another debugger even should not nest, but simply
|
|
print the error, skip the breakpoint, etc as appropriate.

"values show"
