global objects inhibit fold functions
|Created on||Oct 12, 2006 10:59|
This bug is a conceptual problem but feels very much wrong... if we introduce a print in a function used within a fold, the subsequent change in signature inhibits the use as fold and thus leads to a strange error message: ...function not found..... Since all overloadings of a function are treated uniformly, the offending print may even occur in a fold-irrelevant overloading only. I am not sure how to handle this problem nicely:-( I would assume that, in principle, this problem could be solved in a rather complex modification of fold-wls using propagate or so.....
