Thanks for this request. I'm surprised it has not been requested before, but I did not find any dupes. Right now we're working on a major performance overhaul, but improved refactoring is one of our most requested features. |

A few considerations for the design of this feature. Let f be the candidate function.
These concerns aside, I think it would require very little effort to start with something imperfect and iterate from there. Another interesting problem is automatically simplifying the inlined body based on knowledge of the arguments. e.g. a range over a slice or map that it known to be nil can be deleted. Simplification of a block of statements might be a useful feature in its own right, independent of inlining. |

About once a week I look for the Inline Method refactoring in VSCode.
If this could be added that would be super!
