Handle bind (=?) errors in without statements differently
...
Keeps track of the current error variable at compile time,
instead of using a pointer to the error variable at runtime.
Employs a trick with an unused type parameter to ensure that
invocations of the bindFailed() macro are expanded after
captureBindError() is expanded.

Accept only optional and reference types as RHS of =?
...
The fact that `option(x)` works for non-reference types (being an alias
for `some`) is an stdlib's design mistake that bites us here.

tuple binding and unpacking support ( #29 )
...
* tuple binding and unpacking support
* support tuple binding in nim < 1.6
* Use ? instead of Option[] in tests
* Test binding of optional tuple, not just tuple
* Add tests for tuple unpacking of Result
* Remove unused import
* Rearrange tuple binding code
Introduce separate proc for creation of unpacking
statement.
Use `quote do` to make code as similar as possible
to the `bindLet` and `bindVar` templates.
* Add tests for failed tuple bindings

Rename chaining and indexing operators
...
Chaining operator is now `.?`
Indexing operator is now `.?[]`
Reason: interoperability with the binding `=?` operator.
Chaining and indexing now have lower operator precedence
than binding, ensuring that expressions such as `if a =? b.?c`
work as expected.
