Hello,

Older version of sumtype accept this code:

void main(){
    import sumtype;
    alias Val = SumType!(bool);

    const bool b = true;
    Val val = b;  //fail in newest version
    val = b;      //fail in newest version
}

but new version need exact type:


void main(){
    import sumtype;
    alias Val = SumType!(bool);

    bool b = true;   //cannot be const
    Val val = b;
    val = b;
}

is it bug in new version or old version?

It's a bug in the new version. Thanks for reporting. I've opened 
an issue on Github for this:
