 The implicit targets of the current @continue@ and @break@, \ie the closest enclosing loop or @switch@, change as certain constructs are added or removed.
 
-\subsection{\texorpdfstring{Enhanced \LstKeywordStyle{switch} Statement}{Enhanced switch Statement}}
-
-\CFA also fixes a number of ergonomic defecits in the @switch@ statements of standard C. 
-C can specify a number of equivalent cases by using the default ``fall-through'' semantics of @case@ clauses, \eg @case 1: case 2: case 3:@ -- this syntax is cluttered, however, so \CFA includes a more concise list syntax, @case 1, 2, 3:@. 
-For contiguous ranges, \CFA provides an even more concise range syntax as well, @case 1~3:@; lists of ranges are also allowed in case selectors. 
-
-Forgotten @break@ statements at the end of @switch@ cases are a persistent sort of programmer error in C, and the @break@ statements themselves introduce visual clutter and an un-C-like keyword-based block delimiter. 
-\CFA addresses this error by introducing a @choose@ statement, which works identically to a @switch@ except that its default end-of-case behaviour is to break rather than to fall through for all non-empty cases. 
-Since empty cases like @case 7:@ in @case 7: case 11:@ still have fall-through semantics and explicit @break@ is still allowed at the end of a @choose@ case, many idiomatic uses of @switch@ in standard C can be converted to @choose@ statements by simply changing the keyword. 
-Where fall-through is desired for a non-empty case, it can be specified with the new @fallthrough@ statement, making @choose@ equivalently powerful to @switch@, but more concise in the common case where most non-empty cases end with a @break@ statement, as in the example below:
-
-\begin{cfa}
-choose( i ) {
-        case 2:
-                printf("even ");
-                fallthrough;
-        case 3: case 5: case 7:
-                printf("small prime\n");
-        case 4,6,8,9:
-                printf("small composite\n");
-        case 13~19:
-                printf("teen\n");
-        default:
-                printf("something else\n");

+\TODO{choose and fallthrough here as well?}
