-- `Oneline` ensures multiline arguments are not binpacked
+- `Oneline` ensures multiline arguments are not binpacked, that is, they cannot
+  be on the same line as any other argument; also, if the multiline argument is
+  last and the call site is followed by either a curried argument clause or
+  a chained method, it cannot be on the same line as the next identifier after
+  the closing delimiter
+
+Additionally, when binpacking is enabled (i.e., not `Never`), some nested
+expressions in brackets (if the binpacked clause uses brackets) or in braces
+(if it uses parentheses) wouldn't be indented as would happen in usual cases;
+this logic is always used for `OnelineSjs`, and only for single-element clauses
+otherwise.
