the first half part is :Rafactor inline_var, and second part is :Rafactor extract_var new_var, it is from a nvim plugin refactoring.nvim using treesitter under the hood, I use this two quite frequently to eliminate unnecessary variable as well as introduce new variable for some repeated expression, the problem is it fails (or not accurate) in complex situations, so I wish gopls would support this directly.
What did you see happen?
Currently gopls supports extract a single expression to a new variable, I'd say extract every repeated expression under selection would be more useful, since the latter contains the former.
What did you expect to see?
