Isn't it more test pack for lifting code than reflection? |
Contributor

Well, lifting itself is a pretty small chunk of code. The reflection infrastructure (e.g. tree classes, exposed API, importers, toolboxes) is the most interesting part. That's why in my mental model reflection subsumes reification. Also, most of the tests not only lift the code, but also typecheck, compile and run it, which I think, all relate to reflection and reflective compilation. Finally, rough edges usually appear at junction points between the reflection infrastructure and the compiler, which also suggests that the tests are about reflection more than about anything else. |

The REPL :java -app command is a convenience to locate
the body of DelayedInit code. Now it will look for
new style delayedEndpoints on the class before it
falls back to showing the apply method of the
delayedInit$body closure.

Rather than in implementation of the abstract method in the
expanded anonymous class.
This leads to more more efficient use of the constant pool,
code shapes more amenable to SAM inlining, and is compatible
with the old behaviour of `-Xexperimental` in Scala 2.11,
which ScalaJS now relies upon.

And use this as the target of the default methods or
statically resolved super or $init calls.
The call-site change is predicated on `-Yuse-trait-statics`
as a stepping stone for experimentation / bootstrapping.
I have performed this transformation in the backend,
rather than trying to reflect this in the view from
Scala symbols + ASTs.

And use this as the target of the default methods or
statically resolved super or $init calls.
The call-site change is predicated on `-Yuse-trait-statics`
as a stepping stone for experimentation / bootstrapping.
I have performed this transformation in the backend,
rather than trying to reflect this in the view from
Scala symbols + ASTs.
Once we commit to this change, we can remove the
`lateInterfaces` bookkeeping from the backend, as we no
long will need to add ancestor interfaces as direct
parents to allow use of invokespecial for super calls.

And use this as the target of the default methods or
statically resolved super or $init calls.
The call-site change is predicated on `-Yuse-trait-statics`
as a stepping stone for experimentation / bootstrapping.
I have performed this transformation in the backend,
rather than trying to reflect this in the view from
Scala symbols + ASTs.
Once we commit to this change, we can remove the
`lateInterfaces` bookkeeping from the backend, as we no
long will need to add ancestor interfaces as direct
parents to allow use of invokespecial for super calls.
