Thanks, but that's not all the information I need.  What's missing is
which part(s) of a funcname would you like etags to record.  Do you
want each "Name" component to be recorded, or just some of them?

IOW, if we have foo.bar.baz.more, what should be recorded in addition
to the whole foo.bar.baz.more token?  Just bar.baz.more, or something
else?  What about foo.bar.baz:more?
