Support arithmetic sequences.
...
`from` : [a .. ]
`fromThen` : [a, b .. ]
`fromTo` : [a .. b]
`fromThenTo`: [a, b .. c]
These are needed before supporting list comprehensions (#64 ).

Add kindedVar and take type parameters as HsTyVarBndr'. ( #61 )
...
Previously functions like `class'` and `data'` took their
type variables as `OccNameStr` which let them be passed
as overloaded strings; for example, `data' "Maybe" ["a"] ...`.
Now, they take them as `HsTyVarBndr'`, the same as `forall'`,
and can be constructed with, for example,
`data' "Maybe" [bvar "a"] ...`.
This approach lets them be constructed with either `bvar` (for regular
variables) or `kindedVar` (for kind signatures).
Original patch by ersran9@.

of `module'` and `import'`.

Fix listPromotedTy on lists of one or zero elements. ( #55 )
...
We need the explicit `'` to distinguish from regular lists.
For simplicity, just use it for all type-level lists of
any length.

Add occNameToStr and nameToStr to convert from the GHC types. ( #54 )

Previously it was cumbersome to create an `OccNameStr` from an
`OccName` or a `Name`.

Make tyApp's precedence match -XTypeApplications. ( #41 )
...
The precedence with which GHC parses `@` in expressions changes
depending on whether `-XTypeApplications` is set.
In particular, `(var "f" @@ var "x") `tyApp` var "t"` should
render to `"f x @t"`.

Parenthesize let-expressions inside of do-expressions. ( #38 )
...
The following syntax is not valid, but can be generated by GHC;
```
do let ...
in ...
```
It's not always a problem, if GHC manages to wrap it like
```
do let ... in ...
```
But for consistency, and since this ought to be an uncommon case,
always wrap `let`s in parentheses when they're inside of a `do` statement.

Another follow-up fix for #13 :
- Don't allow pattern bindings in class or instance declarations
- Add `valBind` which *is* allowed in let and where clauses
- Add `valBindRhs` and `patBindRhs`.
