FYI, all those names were inherited from Maclisp. The q at the end of 
the names reflects that they use eq as the comparison function.

Conversely, the functions that use equal have long names like delete, 
member, remove. The consistency is that the fully-spelled-out list 
functions use the fully-spelled-out comparison.
