Therefore, you will not find any syntax for class declarations in the BNF below: classes are constructed by evaluating expressions like “Object subclass:’NameOfNewClass'” etc.
IDL Programming Myths You Need To Ignore
These get added to classes by storing them in a class’s method dictionary. Unary messages have the highest precedence, followed by binary messages, followed by keyword messages. For example:
If the sequence does not include whitespace or punctuation characters,
this can also be written as:
Arrays:
