I am hesitant to doing this. 1) During translation I don't want to touch other code even if it were trivial like the one you suggested. 2) From the algebraic side, OutputForm is a write-only format. Only formatters need to know how OutputForm is structured, i.e. for formatters OutputForm is read-only. For this reason, I would eventually introduce another type like "OutputFormat" which would give reasonable accessor functions. But I haven't yet studied formatters and I guess that OutputFormat wouldn't need the "write-only" features of OutputForm, but it would rather be like read-only SExpression. I'd like to give a new name though to make sure that the data is not changed during formatting. 3) Of course, I don't like "pretend" very much, but it's the first approximation and I hope that can all be cleaned up after all the i-output.boot code is in spad.
