The DEC Kx10 CPU (DECsystem10, DECsystem20), has infinite
indirection with possible indexing at each level.  I myself
have written programs with two levels of indexing.

The 10's (36 bit) architecture is quite nice (by my
standards), and has quite a number of risk-like features.
(foremost benig an extremely regular instruction format).

Too bad it's dying out.
