— Macro: doplist (key value plist &optional result) &body body

This is analogous to dolist, but for plists.
The difference is that a plist is expected and two variable names are required: one for the key and another for the value.

The usual conventions are respected:

• An implicit block named nil surrounds the iteration construct. return may be used to terminate the loop immediately without performing any further iterations, returning zero or more values.
• The body of the loop is an implicit tagbody.
