What is the reasoning behind the design of std.complex? [closed]
immutable float a = 1.1, b = 1.2;
auto c1 = complex(a,b);
auto r1 = c1 + c1; // error, not mutable
Which means that I can have
Complex!(immutable float), but I can never use its
opBinary functions against another instance of
Complex!(immutable float). So, why is std.complex implemented in such a way?
Here is the
opBinary. It calls the
opOpAssign, which won't work with
immutable, hence the error.
Complex!(CommonType!(T,R)) opBinary(string op, R)(Complex!R z) const
alias typeof(return) C;
auto w = C(this.re, this.im);
