... mechanisms⁴

The future mechanism in ABCL/f is similar to the one in Multilisp[2]. The difference is that the former allows the programmers to describe more explicit controls[16]. For example, it can be described when a function should wait for the return value of a future call in ABCL/f.

This is similar to that CLOS metaobject protocol[5] allows users to write their extensions using inheritance.
