Feature request: Variant.trustedGet multiple values

[andre2007]

I have a scenario like this:

There are 2 FMU classes version 1 and two FMU classes version 2.
Version 1 supports a method initialize, while this method is not available in version 2.

I want to call trustedGet like this fmu.trustedGet!(FMU1Slave, FMU1Model).initialize();.
At the specific code line, I know fmu is either FMU1Slave or FMU1Model. Both classes
supports method initialize. It should call method initialize independent whether it is now FMU1Slave or FMU1Model.

/+ dub.sdl:

import mir.algebraic;

class FMU1Slave
{
	void instantiate() {}
	void initialize() {}
}

class FMU1Model
{
	void instantiate() {}
	void initialize() {}
}

class FMU2Slave
{
	void instantiate() {}
	void enterInitializationMode() {}
	void exitInitializationMode() {}
}

class FMU2Model
{
	void instantiate() {}
	void enterInitializationMode() {}
	void exitInitializationMode() {}
}

void main()
{

	Variant!(FMU1Slave, FMU1Model, FMU2Slave, FMU2Model) fmu;
	string fmiVersion;
	bool isCoSimulation;

    if (fmiVersion == "1.0")
    {
        if (isCoSimulation)
            fmu = new FMU1Slave();
        else
            fmu = new FMU1Model();
        fmu.instantiate();
        fmu.trustedGet!(FMU1Slave, FMU1Model).initialize();
    }
    else
    {
        if (isCoSimulation)
            fmu = new FMU2Slave();
        else
            fmu = new FMU2Model();
        fmu.instantiate();
        fmu.enterInitializationMode();
        fmu.exitInitializationMode();
    }
}

Yes, we already have a draft for it. Will be added.

Overload to work with algebraic type sets.

• trustedGet
• get
• constructor

@deviator this may be helpful for the #34

@9il thank you
