It wasn't a copy and paste error - I proved that by redoing it, diffing 
etc - it was ONLY the version issue.

That is incorrect, I reported exactly what I did - I got a GUILE error 
(on an old snippet version) - I probably should have posted the code, 
then it would have been clear straight away - but it wasn't a copy and 
paste problem.

That is a fair comment in general does not apply in this case - the fact 
is that I hadn't remembered the conversion thing and if I had, there 
wouldn't have been an issue . . and it is NOT unreasonable for someone 
coming from other coding regimes not to have upper in their minds: that 
ALL old code has to be converted - this is unusual situation.
