It only compiles fine with the (default) {$t-}. If you add {$t+}, it doesn't compile. Without typed pointers, the result of the @-operator is an untyped pointer, which by definition is assignment-compatible with all other pointer types.
Making {$t+} the default is hard because it could break existing, correct code (e.g., "untypedptr:=@wordvar+1" would result in a pointer 2 bytes after @wordvar instead of 1 with {$t+}).
