It looks that way but he doesn't seem to have got as far as documenting 
errors: the documentation gives several examples of that form and says that 
'error' is a reserved word but says nothing about how you create an error 
of if you can distinguish one error from another:

I'm guessing you can't as FT doesn't appear to have any concept of 
attributes on objects (or even any concept of objects): so far as I can see 
the only types are integers, rationals, intervals and strings (and real 
numbers if you pay real money for them).

Maybe I'm missing something though, because I don't see how you can do 
anything useful with out at least some sort of arrays (unless you are 
supposed to store numbers in long strings).
