Support a definitive flag for Failure that ignores later failures
instead of appending them. This is useful to override the default
behavior of listing the failures of alternative parsers.
Needed an explicit type in PMap to workaround an error.
Need to drop tuple assignment of parser.parsed in input task macro as a workaround
for macro/resetAllAttrs/pattern matching/annotation issue in RC1.
1. Hyphenated labels are still accepted when parsing scoped keys (so 'sbt test-only' still works)
There is currently no timeline for removing this support for hyphenated keys.
2. Only camelCase is shown for tab completion.
3. AttributeKey.rawLabel provides the unnormalized label.
This should only be used to implement support for accepting hyphenated keys as input for compatibility.
4. AttributeKey.normLabel provides the normalized label (hyphenated converted to camelCase)
Similar to task macros, the parsed value is accessed by calling `parsed`
on a Parser[T], Initialize[Parser[T]], or Initialize[State => Parser[T]].
Values of tasks and settings may be accessed as usual via `value`.
That is, implement Initialize[Task[T]].flatten correctly.
This requires preserving the transformations applied in a scope so that
they can be applied to an Initialize value after static settings have been
evaluated.
* use normal TypeTree constructor
* remove unnecessary 'with Singleton' in macro utility
* integrate changes suggested by @xeno-by
* add refVar back and call asTypeConstructor instead of asType to refer to a type variable
1. KList[M[_]] now instead of KList[HL <: HList, M[_]]
a. head, tail work properly in this variant
b. disadvantage is that full type not easily transformed to new type constructor
2. AList abstracts on K[L[x]], a higher order type constructor.
A. Instances written for:
a. KList
b. Seq[M[T]] for a fixed T
c. TupleN
d. single values
e. operate on one type constructor when nested
B. Main disadvantage is type inference. It just doesn't happen for K[L[x]].
This is mitigated by AList being used internally and rarely needing to construct a K.
