This SRFI defines parameter objects, the
procedure make-parameter
to create parameter objects and the
parameterize
special form to dynamically bind parameter
objects. In the dynamic environment, each parameter object is bound to a
cell containing the value of the parameter. When a procedure is called
the called procedure inherits the dynamic environment from the caller.
The parameterize
special form allows the binding of a
parameter object to be changed for the dynamic extent of its body.
