Café,

For those who haven’t seen it Uday Reddy has a comprehensive answer to a
request
to explain referential transparency on Stack Overflow.


http://stackoverflow.com/questions/210835/what-is-referential-transparency/9
859966#9859966

For good measure he finishes with a rather scathing assessment of functional
programmers’ claim to ownership of RT:

    Functional programmers don't know much of this research.
   Their ideas on referential transparency are to be taken
   with a large grain of salt.

Marvellous! 'Tis rare to find such a robust assessment combined with
understanding (and it certainly makes me think a bit).

Have we become a bit complacent about RT?

Chris
