trpl: additions & fixes for syntax index.

Browse Source 
* `const`: Add reference to raw pointers
* Change `expr!(...)` etc. examples to use `ident` instead.
  *Technically*, it should be `pat`, but that's not how it works in
  practice.
* `|`: add reference to closure syntax.
* Closure syntax entry.
* Indexing and slicing entries.
