 In your previous mail you wrote:

   Clearly the Wikipedia definition of strict:
   	f(bottom) = bottom
   is rubbish when applied to a mathematical function like 'sin', 
   since bottom isn't a valid argument, but it makes sense
   for 'sin' in the programming language sense.
=> as a student many years ago of the inventor of the "strictness" concept
I don't understand your statement: a strict function is simply a function
which uses its argument. In semantics this is caught by f(bottom) = bottom
where bottom is a semantics value (not a real one) so by definition always
a valid argument.


PS: the inventor is Jean Vuillemin and of course the strictness concept
is central in the evaluation strategies.
