+The previous, experimental macro system has been dropped. Instead, there is a cleaner, more restricted system based on two complementary concepts: `inline` and `'{ ... }`/`${ ... }` code generation.
 `'{ ... }` delays the compilation of the code and produces an object containing the code, dually `${ ... }` evaluates an expression which produces code and inserts it in the surrounding `${ ... }`.
 In this setting, a definition marked as inlined containing a `${ ... }` is a macro, the code inside the `${ ... }` is executed at compile-time and produces code in the form of `'{ ... }`.
 Additionally, the contents of code can be inspected and created with a more complex reflection API (TASTy Reflect) as an extension of `'{ ... }`/`${ ... }` framework.

 In our experience, macros and changes in type and implicit argument inference together cause the large majority of problems encountered when porting existing code to Scala 3. The latter source of problems could be addressed systematically by a tool that added all inferred types and implicit arguments to a Scala 2 source code file. Most likely such a tool would be implemented as a Scala 2 compiler plugin. The resulting code would have a greatly increased likelihood to compile under Scala 3, but would often be bulky to the point of being unreadable. A second part of the rewriting tool should then selectively and iteratively remove type and implicit annotations that were synthesized by the first part as long as they compile under Scala 3. This second part could be implemented as a program that invokes the Scala 3 compiler `dotc` programmatically.
 
-Several people have proposed such a tool for some time now. I believe it is time we find the will and the resources to actually implement it.

+The inline method is a "blackbox" in the sense that details of its implementation do not leak out.
 But if a `transparent` modifier is given, the expansion is the type of the expanded body. If the argument `b`
 is `true`, that type is `A`, otherwise it is `B`. Consequently, calling `m` on `obj2`
 type-checks since `obj2` has the same type as the expansion of `choose(false)`, which is `B`.
