There’s a few tests in the git repository for Tcl.pm which aren’t in the releases (not in MANIFEST?): dispsosal-subs-[abcdef].t, memleak-a.t, and set-callback.t.
Are these being excluded on purpose (i.e. they are developer-only rather than installation tests), or should they be included in releases? Also, some of them (disposal-subs-a.t and memleak-a.t) use Devel::Refcount, which isn’t declared as a test dependency in Makefile.PL.
