Thanks, it's useful to know other people's thinking for comparison ---
to be clear, what I was hoping for and lacking was something along the
lines of:

echo /blah/blah/blah/**/*.oogabooga(<stuff-here>)

even if <stuff-here> wasn't quite as short as :t2.  I could live with a
few more characters but a loop or complicated substitution would lead me
to propose adding the new code instead.
