No idea, but in any case the new version seems nicer :-) Both 2.11 and 2.12
will happily generate a `typeTag` for `Any`, though, so that wouldn't
immediately explain it. To see what was actually inferred, you could compile
with `-Xprint:typer` (ideally after a full compile and then just making this
file recompile incrementally).
