Mixim template can only introduce declarations, not statements, a workaround is a lambda called in place.

mixin template test(A...){

}

extern(C) void main(){
        mixin test!123;

Except that you can't use tuples for that, a working sample:

mixin template test(alias A){
        __gshared a = A;
        int dummy = (){ a++; return 0; }();
}

extern(C) void main(){
    mixin test!123;

    import core.stdc.stdio;
    printf("%d", a);
}
