[dependabot]

Bumps scala.version from 2.12.9 to 2.13.3.
Updates scala-reflect from 2.12.9 to 2.13.3

Release notes

Sourced from scala-reflect's releases.

Scala 2.13.3 is primarily a bugfix release.

It also includes:

• improvements to warnings and linting
• experimental -Xasync support

For more detail, read on.

Behavior changes

• Symbol#toString is now Symbol(foo) instead of the deprecated single-quote form 'foo (#8933)

Bugfixes

• Fix 2.13-only bug in Java collection converters that caused some operations to perform an extra pass (#9058)
• Fix 2.13.2 performance regression in Vector: restore special cases for small operands in appendedAll and prependedAll (#9036)
• Increase laziness of #:: for LazyList (#8985)
• Allow trailing backslash in string interpolators (#8942)
• Respect @uncheckedVariance in higher-kinded types (fixing 2.13.2 regression) (#8938)

Warnings and linting

• Deprecate auto-application of (non-Java-defined) methods with a single empty parameter list (#8833)
  • The PR has instructions for suppressing the warning if it is unwanted
• Warn by default on mismatch of presence/absence of an empty parameter list when overriding (#8846)
  • -Xlint:nullary-override is no longer accepted, since this now warns by default
• Discourage multi-argument infix syntax: lint applications (x op (a, b)), also lint operator-name definitions (#8951)
• Fix @nowarn to use correct semantics for & (#9032)
• Make -Wunused:imports work again even when -Ymacro-annotations is enabled (#8962)
• Replace -Wself-implicit with -Xlint:implicit-recursion (#9019)
• Under -Xsource:3, disallow auto-eta-expansion of SAMs (#9049)

Experimental -Xasync

This successor to scala-async allows usage with other effect systems besides scala.concurrrent.Future.

• Compiler support for scala-async; enable with -Xasync (#8816)

We will publish a blog post with more detail on this work by @retronym, building on his earlier collaboration with @phaller. In the meantime, see the PR description.

This feature will also be included in the 2.12.12 release.
