That won't work; adding the do {...} while (0) negates the continue in the
code block.

After reading the manual, it is indeed undocumented that DEBUG, RETURN and ERR
have the same semantics for `source' and function calls. Or perhaps it's
documented, but I didn't take the time to read it all.
There information related to DEBUG is scattered across man bash. Some of the
relevant stuff

It doesn't matter whether the old DEBUG trap runs
There is no bug. Simply, your expectations on when the DEBUG trap runs are
wrong.
The `script2' I provided ran with set -T is the closest you'll get to what you
expect, but, since DEBUG runs *before* the source command, it'll not work as
you want.

Absolutely right, and I should have included that

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:
Read about set -T in the manual. Also, you have an error in your trap
definition. The $1 inside "..." will expand at *definition* time, not when the
trap is executed. See:
dualbus@yaqui ~/t % cat script
echo '
trap "echo $1" DEBUG
' > ./trapcmd
source ./trapcmd first
