One has to be careful about the use and interpretation of ellipses.
For example the Mathematica documentation for Compound Expression says
that
expr_1 ; expr_2 ; ?
evaluates the expr_i in turn, giving the last one as the result.
Would this statement, interpreted very literally using a precise
definition of the ellipsis symbol, cover both
expr_1 ; expr_2 ; expr_3 ; expr_4 ;
and
expr_1 ; expr_2 ; expr_3 ; expr_4
or just one of these? (Which one?)
_Is there_ a precise definition of the ellipsis symbol? (in English, or
in Mathematica)
Is " ; " technically an expression? (in Mathematica)
