Not so easy. You need to find where a temporary is being reassigned to which
means some additional expression analysis. I think that more 'thinking' need
to be done concerning this refactoring for C++. For example:

double temp = 2 * (height_ + width_);
print( temp );
computeArea( height_, width_, temp );
...

void computeArea( double height, double width, double &area )
{
    area = height + width;
}

computeArea() is an indirect assignment to the local variable temp...

Also, I don't get what you means by 'determining the type of  a variable'.
For a given local variable identifier, we can already find its declaration
(see ScopeHolderTest) and therefore its type. So the real issue is
determining where a temporary is being reassigned to.
