Declarations

The special form declare  is available, but all declarations are currently ignored by the interpreter and the compiler, including special declarations.

It may be fairly easy to add proper handling of special declarations to the byte code compiler, but adding it to the interpreter will cut speed unless the code is rewritten in the spirit of macro displacement.

The function proclaim  is available. Currently only special proclamations have an effect. There is no portable way to take back a special proclamation.

Macros for the special forms locally  and the  are available. They currently ignore declaration and type information.
