 The `@bangbang` macro rewrites expressions to use out-of-place operations if needed. The
 following operations are supported:
 
-    1. `copyto!(y, x)`
-    2. `x .(+/-/*)= <expr>`
-    3. `x ./= <expr>`
-    4. `copy(x)`
-    5. `x .= <expr>`
-    6. `@. <expr>`
+  1. `copyto!(y, x)`
+  2. `x .(+/-/*)= <expr>`
+  3. `x ./= <expr>`
+  4. `copy(x)`
+  5. `x .= <expr>`
+  6. `@. <expr>`
+  7. `x = copy(y)`
 
 This macro also allows some custom operators:
 
-    1. `×` (typed with `\\times<tab>`): This is effectively a matmul operator. It is
-       rewritten to use `mul!` if `y` can be setindex-ed else it is rewritten to use
-       `restructure` to create a new array. If there is a `vec` on the rhs, `vec` is also
-       applied to the lhs. This is useful for handling arbitrary dimensional arrays by
-       flattening them.
