It doesn't work without it, though quote could be used as an alternative:

'(quote (1.6 1.5 0.4 1.5 0 0 2 0
               0.4 0.75 1.6 0.75 2 0 0 0))

If you're talking about Mats's recent comments on \translate, it seems
to me the conclusion was precisely the opposite, apart from the cases
where backquoting would be required.
