Agree on it being great and innovative. But I fail to see
usefulness with current design. Can you provide examples how
current pure design allows for better code / optimizations?
Strongly pure functions can call weakly pure function while keeping
its properties.
So it loosen the constraint on strongly pure function while keeping
the benefit.
It does not answer my question. Why "pure" keyword is useful in D if
it does not guarantee that compiler will verify functional purity of
you code and does not guarantee relevant optimizations?
Beauty of concept is useless without practical application.
It isn't beauty of concept. Strongly pure function exhibit from an
external point of view the properties of pure as in functional
programming.
Except you can't be sure that your function is strongly pure with
current design.
I would venture that you are being confused. This seems to indicate
insufficient documentation for 'pure'.
