I’ve focussed mostly on how effects relate back to exceptions and async code, since those are control-flow constructs that I (and probably you) are most familiar with. I haven’t given much thought to what it would be like to write code where all I/O is handled through effects. If you had to annotate every single function and function call that you wanted to do I/O, I imagine that would get really tedious. If the language had good type inference on the required effects, then it might not be so bad.
At the heart of BuildKit is LLB (Low-Level Build definition). Think of it as the LLVM IR of build systems. LLB is a binary protocol (protobuf) that describes a DAG of filesystem operations: run a command, copy files, mount a filesystem. It’s content-addressable, which means identical operations produce identical hashes, enabling aggressive caching.

在沈丹阳看来，所谓“供强需弱”，其实消费领域也不完全是这个问题。比如，消费供给就有弱的一面，需要在供给上着力培育消费新增长点，实施服务消费提质惠民行动，加力推进消费新业态新模式新场景试点，大力培育文旅、汽车后市场、体育赛事、演艺经济、情绪式体验式服务等能够更好满足需求的消费场景。同时，分类施策支持下沉市场消费渠道升级和场景创新，推动品牌连锁加快布局，进一步激活下沉市场消费潜力。
