As you said, "CLIST has no syntax for quoted text." And, apparently, no
way to escape special characters.

Use SIGNAL ON NOVALUE to prevent that. It's how I begin every REXX program.
My worst case: Once, as an experiment or accidentally I coded
"do" instead of "DO". It failed with a message like:
ILLEGAL STATEMENT: "DO".
That's wrong two ways:
i) "DO" is not illegal.
i) "DO" is not what I coded.
CLIST has a mortal terror of lower case.
