I see what you like about having a FixedPoint type and being able to say
a = b.Multiply(c)
This gives you the flexibility to add modules as you need them by dumping
all the work onto the compiler, which is not a bad place if you are not the
compiler writer.
It does not work in all cases, though; you will probably have a hard time
implementing a FloatingPoint type, for example, unless the new firmware
supported these natively.
There seems to be a rather large gray area surrounding which features are
needed and which features would be nice to have. My opinion is somewhat
split on this topic - if a new byte code is designed now, I know there
is a good chance that design will not change much, severely influencing how
the byte code can and will be used later on; I also know that starting off
with an overly complicated byte code is a mistake, it will never get
finished.
