overall exceeds FORMULA_MAXTOKENS (8192) in the generated RPN
code, hence an ocStop is encountered as factor token.
(this cries for generating subroutine call token arrays where each
named expression could have their own RPN code and interim results
could be remembered for each while interpreting within one formula
cell; just dreaming..).
