Instance Method Details
#expand_elses(branch) ⇒ Object
‘elsif` branches show up in the `node` as an `else`. We need to recursively iterate over all `else` branches and consider all but the last `node` an `elsif` branch and consider the last `node` the actual `else` branch.

#expand_when_branches(when_branches) ⇒ Object
‘when` nodes contain the entire branch including the condition. We only need the contents of the branch, not the condition.
