This module allows you to delay the computation of values, usually so you
|
|
can change your mind about the returned value. Its a sort of time travel.
|
|
|
|
The values returned by this module are overloaded objects which can be
|
|
operated on like numbers, strings, or booleans but aren't actually made
|
|
"real" until you use them in some context that requires that they be
|
|
computed first.
|
|
|
|
As an aide to debugging and to prevent time paradoxes, the default
|
|
postpone() function's effect is that once a value has been computed, it
|
|
ceases to be overloaded and all of the input variables to it are turned
|
|
read only.
