Re: [ddlm-group] Fwd: Fwd: Searching for a compromise on eliding

Putting aside personal taste, I can see that using a completely different token as a delimiter
will markedly reduce the chances that eliding will actually need to be employed in order to accommodate
all the delimiters in a data value. So changing to e.g. `` instead of ''' etc. may indeed allow us to
drop the python discussion completely - dropping all the extra 'baggage' that comes with python?

Perhaps F' with `` is the way forward - I dont imagine many (any) CIFs contain `` ?

Cheers

Simon

Proposal G is derived from F', which has the simple rule that n
backslashes before <eol> is replaced by n-1 backslashes and <eol>
unless there is only 1 backslash, in which case both backslash and
<eol> are removed.  So the internal representations of these three
strings are:

<start>line 1 line 2<finish>

<start>line 1 \
line 2<finish>

<start>line 1 \\
line 2<finish>
