I think it does if ses counts lines to access the ses-cell rows --- TBC.

I need the symbol, because for instance if the symbol is ses-dashfill or
math-format-value, then I would directly call the corresponding
symbol-function rather than indexing the hash map.
So I need some trick to know whether the symbol is a function name or a
printer function. One simple trick would be to set the symbol value slot
to some fixed value, e.g. to symbol :ses-printer. Another way would be
to try the hash-map first and then check whether it is a function as a
fallback, or the other way round. I could also set some property to the
symbol...
My preference would be to set the symbol value to some specific
indicator, I feel that the execution time would be faster this way.
But maybe I should not care too much about this: one could improve speed
by caching all printer functions directly in the cell object for faster
access, and keeping printer definitions in a cell property.
