Hi, I did, over and over. :) I didn't see anything about -T being
unnecessary the first time you set a trap from a sourced script, but
being required every time thereafter.
(quick parentheses: I'm not quite sure if sourcing a file is supposed
to share ALL script contexts, or be more like calling a function. If
the former, -T would never be required, and if the latter, -T would
always be required. Just curious, is this documented anywhere?)

But I want it to expand at definition time. That makes it easy to see
if the trap call worked or not.
Here's the bug with explicit expansion:
echo "trap 'echo first' DEBUG" > script1
echo "trap 'echo second' DEBUG" > script2
. ./script1
. ./script2
I would expect the trap calls in script1 and script2 to behave
identically. Instead, script1's trap is set, but script2's trap is
ignored.
Thanks for the reply.
