Does anyone know how exactly Bun is used by Anthropic? Is it a part of Claude Code?
It seems to be used by anthropic as a way to shift the discussion window into it being acceptable that you yolomerge millions of lines.
the `claude` binary is essentially a packed copy of bun + the js code, so this will replace the native runtime part of claude code.
