import std.stdio;

struct Temp {
  this(float ctorPar) {
  }

  this(double ctorPar) {
  }

  void buggy(float val) const {
    writeln(val);
  }

  void buggy2(double val) const {
    writeln(val);
  }

  void working(real val) const {
    writeln(val);
  }
}

void main() {
  Temp(7.f).buggy(2.);  //!<- val == ctorPar
  Temp(7.f).buggy2(0.); //!<- val is some mixup of ctorPar
  Temp(7.f).working(2.);

  Temp(7.).buggy(2.);   //!<- val == 0
  Temp(7.).buggy2(2.);  //!<- val == ctorPar
  Temp(7.).working(2.);
}

------

Only the functions taking a real gets called with the correct parameter value.
The other two are influenced by the value to the ctor.
