I agree, particularly considering that his original objection appeared to be about the inability to escape the quote delimiter, not necessarily about not having a general escape syntax:

I agree that Ralf is right: it would be much better for CIF2 to solve the CIF1 problem that some text cannot be expressed as a CIF data value.

Ralf's comments give me no reason to believe that he would demand a particular approach to solving the problem.  As I read him, Ralf proposed full Python syntax as a possible solution, not as a necessary one.  Perhaps one of you in direct contact with him would be so kind as to inquire?  Indeed, the Python proposal is only one of two distinct proposals he put on the table himself.  The other is quoted above, though it's a bit vague; Proposal A is one reasonable concrete form of it.

Consider also that the more complex the solution we choose, the more likely it is that some other COMCIFS member would express reservations.
