One specific (but synthetic) example I was thinking of was along the same lines:
loop_
_amino_acid.code
_amino_acid.optical_rotation_direction
'ALA' +
'ARG' +
'LEU' -

It is not. Those are " ' _ $ [ {
If the proposal is adopted then adding + to that list would reduce the added complications for parsing. That would be incompatible with using the optional leading + with numeric values, however.
