since we are now ruby sorcerers, not just wizards, we remove the Parfait module in the compiler (Still have to avoid the name clashes)

# In rubyx everything truely is an object. (most smalltalk/ruby systems use a union
|
|
# for integers/pointers that are called objects, but are really very different)
|
|
#
|
|
# Objects have type as their first member. No exception.
|
|
#
|
|
# So where is the data? In DataObjects. DataObjects are opague carriers of data.
|
|
# Opague to rubyx that is. There is no way to get at it or pass the data around.
|
|
#
|
|
# To use Data, Risc instructions have to be used. Luckily there is not soo much one
|
|
# actually wants to do with data, moving it between DataObject , comparing and
|
|
# logical and math operation that are bundled into the OperatorInstruction.
|
|
#
|
|
# For safe access the access code needs to know the length of the data, which is
|
|
# encoded in the class/type name. Ie An Integer derives from Data4, which is 4 long
|
|
# ( one for the type, one for the next, one word for the integer and currently still a marker)
|
|
#
|
|
# DataObjects still have a type, and so can have objects before the data starts
|
|
#
|
|
# A marker class
