Bug 18663 – std.random.isSeedable has false positives

Example of wrong behavior: ```d int main() { import std.random : isSeedable, isUniformRNG; struct Rnd { @property uint front() {return 0;} @property bool empty() {return false;} void popFront() {} void seed(uint val){} enum isUniformRandom = true; } static assert(isUniformRNG!Rnd); static assert(isSeedable!(Rnd, ulong)); // Passes erroneously. Rnd rnd; rnd.seed(ulong.max); // Compile-time failure because seed isn't callable with ulong. return rnd.front; } ```
