*	blackbox and whitebox macros	Eugene Burmako	2013-11-12	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This is the first commit in the series. This commit only: 1) Splits Context into BlackboxContext and WhiteboxContext 2) Splits Macro into BlackboxMacro and WhiteboxMacro 3) Introduces the isBundle property in the macro impl binding Here we just teach the compiler that macros can now be blackbox and whitebox, without actually imposing any restrictions on blackbox macros. These restrictions will come in subsequent commits. For description and documentation of the blackbox/whitebox separation see the official macro guide at the scaladoc website: http://docs.scala-lang.org/overviews/macros/blackbox-whitebox.html Some infrastructure work to make evolving macros easier: compile partest-extras with quick so they can use latest library/reflect/...
*	SI-6187 Make partial functions re-typable	Jason Zaugg	2013-02-07	1	-0/+18
	- `New(tpe)` doesn't survive a `resetAttrs` / typecheck; use a name instead. - Abandon the tree attachment that passed the default case from `typer` to `patmat`; this tree eluded the attribute reset performed in the macro. Instead, add it to the match. Apart from making the tree re-typable, it also exposes the true code structure to macros, which is important if they need to perform other code transformations. - Install original trees on the declared types of the parameters of the `applyOrElse` method to ensure that references to them within the method pick up the correct type parameter skolems upon retypechecking. - Propagate `TypeTree#original` through `copyAttrs`, which is called during tree duplication / `TreeCopiers`. Without this, the original trees that we installed were not visible anymore during `ResetAttrs`. We are not able to reify partial functions yet -- the particular sticking point is reification of the parentage which is only available in the `ClassInfoType`.
