Leonardo de Moura 19e4c30542 feat: elaborate new let decl 
We can now write
```lean
syntax "case!" ident ":" term "with" term "," term : term
macro_rules
| `(case! $h : $c with $t, $e) => `(let $h := $c; cond $h $t $e)
```

Before the series of commits to change `let` syntax, the
quasiquotation `(let $h := $c; cond $h $t $e)
produced the weird error message "`;` expected" at ":=".
The problem was that $h was matching the now deleted "nonterminal"
```lean
def letIdDecl         := parser! try (letIdLhs >> " := ") >> termParser
```
This was not a bug, but a side-effect on how the `let` syntax was
declared.
