• main function check version and then run require statement dynamically?

runtime

• use fixed version number under project ./node_modules

development

how to switch the global lsc version, something like nvm for LiveScript

maintenance

this change made an impression unstable API or unclear update policy.

its welcome those change to be useful, and maybe reasonable for the change.
but there is a negative side effect too.

It's important QA/CI to the keep quality of code, for maintenance.
at this point, JavaScript language spec is stable, but Node.js API stability is variable.
they show stability level at least. (e.g. they suggest use domain for async error handling in document, but developer told they may remove domain module, no one seem use.)
