The 8-bit PIC microcontrollers have a separate return stack. The PIC10 has a 2-level stack, the PIC16 has 8 levels, and the PIC18 has 31 levels. But these chips range from 16 bytes of RAM and 256 words of flash for a PIC10, through 64-256 bytes of RAM and 1-4K words of flash for a PIC16, up to 2KiB of RAM and 16K words of flash for a PIC18, so you usually run out of something else long before the maximum stack depth becomes an issue. -- http://mail.python.org/mailman/listinfo/python-list
