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.
