Allow write-able access to function RPN interpratation
Whenever there are complex formulas it requires major effort for the developer introducing proper/robust parser whenever these formulas should be processed correctly without breaking the report.
Giving developers access to RPN interpratation of the formulas would significantly help to support following use-cases:
- Easier and robust implementation of custom UI/UX for Function wizard, i.e. UI can support editing of very complex formulas without breaking the report
- Easier migration/update of existing custom functions in complex scenarios to support new features, one sample is company having addin for many years and want to migrate the formulas to Dynamic Arrays without throwing burden on customers
Just to explain (2) - of course one approach is to simply introduce new formulas and let the migration on customers (huge effort for them if they have hundreds/thousands of big reports).
Second is to provide automatic migration in the addin - but that means huge investment in building proper parser to support all complex scenarios similar to building parser for nice/intuitive and robust function wizard...
