14.2. Naming

In addition to 'create', there are a number of other naming conventions:

NOTE: Classes with immutable semantics are given their 'mathematical' names: STR, VEC, $SET. Mutable classes that represent a value that may change over time have the prefix 'OB': OBSTR, OBVEC, $OBSET. When both versions exist, the method 'value' is used to take a 'snapshot' of the object's state, converting from the mutable to the immutable form.
