Collectively, these types are fairly common in the context (about 400 in the default context). Defining __slots__ for them so that they don't need a __dict__ object to store attributes results in a fairly inconsequential saving of memory with the default context, but likely could result in significant savings depending on the amount of data yaql is operating on.

YAQL: Yet Another Query Language
YAQL (Yet Another Query Language) is an embeddable and extensible query language, that allows performing complex queries against arbitrary objects. It has a vast and comprehensive standard library of frequently used querying functions and can be extend even further with user-specified functions. YAQL is written in python and is distributed via PyPI.
