Hi everyone,
is there a deeper reason why thin_tac allows schematics in the pattern,
but no underscores?

thin_tac belongs to the res_inst_tac family, which has the following
comment in the ML sources: (* FIXME cleanup this mess!!! *) -- it means
that this is highly non-canonical within Isar, and dummy patterns via
underscore belong to certain Isar syntax policies that are not observed
here.
After so many years of these remaining oddities in the sources, there is
actually a perspective to overcome it all, and have proof methods with a
goal focus that fit into Isar conceptually -- as part of the Eisbach work.
