Thanks David!  Doh! it had to be something simple and obvious.

And that's why my orginal test program worked fine - it was correct.

I see ruby suffers from the same problem as perl -- just about anything 
is valid syntax, so it compiles but the semantics are not quite what you 
intended ;)

In a past life I spent half each day for several years as a programming 
consultant in a large university (in the days of mainframes) I lost 
count of the number of times that I had people come in with a listing of 
their program, lay it out in front of me and start explaining the latest 
incomprehensible behaviour then suddenly stop, go bright red and quickly 
gather everything up muttering that they now knew what the problem was. 
I know how they feel :)

Russell (who has just spent an hour or so carefully paring down his 
program to 10 lines that illustrates the problem :)
