qualifiers illegal on the LHS of a function" fixing this issue:

- Fix issue 12931: Make ambiguous qualifiers illegal on the LHS of a function

  This has been a pain point for many D users for years,
  both new and old, as can be seen from the discussions on the issue.
  It is however a potentially disruptive deprecation.

  Note: The test for issue 5962 in test/runnable/xtest46.d has been
  removed as the issue was only present with prefix syntax.
