Automatically displaying the name of the variable in the title of the plot with ggplot2

I wonder how to automatically display the variable name of the title of the plot with ggplot2. Like in the example below how can I show the names of variables in the main title?

qplot(mpg, wt, data=mtcars, main = "Scatter plot of mpg vs wt")

There's no hidden variable here, you can create a wrappper for qplot to accomplish this: 

scatter.qplot <- function(x, y, d) {
qplot(get(x),get(y),data=get(d),main=paste("Scatter plot of",x,"vs",y,sep=" "))
}

scatter.qplot("mpg","wt","mtcars")
