Line 40:
Different dialects use different schemes for source code management and various source code exchange formats exist: XML based/VisualWorks, zip-archive Monticello, GitHub file based (tonel), etc.).
One common interchange format which all systems support is the original bang-separated "chunk format", which consists of Smalltalk expressions (!) separated by "!" characters. These expressions, when read and evaluated, will reconstruct the original classes, methods or arbitrary objects.
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. This is very similar to the way Lisp or Scheme code is loaded by a read-eval-print loop.
