(cherry picked from commit f6a5c93)
Update SBT for the warn command, now assumed by sbt-extras
Don't bother adding `{ ...; () }` if we can use the original tree(s) instead,
e.g. if the last tree in `...` conforms to `Unit`.
This makes the debug output of the macro a little easier to read.
(cherry picked from commit de641dc)
If we blindly splicing `{..$stats, ..$generatedCode}`, and the last
expression in `$stats` is of type `Nothing`, we'll incur a dead
code warning when typechecking the block.
This commit:
- introduces a helper method to augment user-written stats with
synthetic code
- Emit a try/finally in that code (so we advance the state, even if we
are about to exit the state machine in the async-block global
exception handler
- Hide `Nothing` typed expressions from the dead code analysis
by wrapping them in an `expr: Any`
Fixes scala#150 (the part reported in the comments, not the original ticket.)
This avoids leaving .class files in the working directory after running the test. (cherry picked from commit 5bb93b0)
And remove unused code. (cherry picked from commit 7238bc1)
