In Bugzilla I have proposed that if you call a pure function and you don't
assign its return value, then you have a bug, like the similar present in D for
unassigned expressions.
This should be restricted to *strongly* pure functions. Weakly pure
functions may have its major effect sent out via the input arguments, so
ignoring the return value could make sense.
import std.stdio;
pure double[] set(double[] x, int index, double e) {
x[index] = e;
return x;
}
void main () {
auto j = new double[](3);
j.set(0, 1.5).set(1, 2.5).set(2, 5.1);
writeln(j);
}
BTW, which Bugzilla entry you are talking about?
