That reminds me of the Microsoft Basic that was put on the first IBM 
PCs.  It consisted of a lot of machine-code routines in ROM, and a small 
executable that invoked them.  Later versions simply made less use of 
the ROM, gradually replacing those routines with others.

Of course that wasn't Basic code itself replacing Basic code...
