Documentation

List associating function properties to their macro expansion.

Each element of the list takes the form (PROP FUN) where FUN is a function. For each (PROP . VALUES) in a function's declaration, the FUN corresponding to PROP is called with the function name, the function's arglist, and the VALUES and should return the code to use to set this property.

This is used by declare.

Probably introduced at or before Emacs version 24.3.
