Line 39: Smalltalk environments are open - almost every aspect of the language and IDE can be changed, enhanced and customized. This includes object representation, metaclass and reflection facilities, language syntax, exception handling and the IDE itself. For this reason, Smalltalk has traditionally been a testbed for new language features, mechanisms and patterns. Smalltalk is a very high level language, which almost completely hides any underlying machine representation. Implementation details such as integer size, pointer size, byte order etc. are ~~invisible~~transparent. The numeric tower is highly polymorphic, allowing for transparent use of arbitrary large integers, fractions, floats, complex numbers etc. Smalltalk is a very late bound language. Object types, classes, references etc. are resolved at execution time, and can be dynamically changed.
