Not for now. With Thierry we've started to think about a stack-based expression evaluator which would make it trivial to concat strings and perform many other operations but we found that it will suffer from some deep problems like retrying failed fetches. Thus I think that for now we'll have to only implement a "concat" converter supporting a constant string and another one to concat a variable. Maybe we can call them "strcat()" for constant strings and "varcat()" for variable names. Is anyone interested in working on this ? Willy
