And there are no looping constructs at all in CPP.  You flat out can't
do a generalized for loop with the macro language, for example.  Its
symbols also do not map 1-1/onto symbols used by the dts files.  It
can only grok macros you define for it, so it has no way of knowing
many useful things that dts just knows.

Basically, it is using a hammer to pound screws in.  Sure, it seems to
work, but the results are shoddy.
