* `memoise()` now signals an error if an already memoised function is used as
input (#4, @richierocks).
* `has_cache()` function added which returns a boolean depending on if the
given call is cached or not (#10, @dkesh).
* Memoised functions now have a print method which displays the original
function definition, rather than the memoisation code (#15, @jimhester).
* A memoised function now has the same interface as the original function,
if the original function is known when `memoise` is called. (Otherwise,
the old behavior is invoked, with a warning.) (#14, @krlmlr)
* The enclosing environment of the memoised function is specified explicitly,
defaults to `parent.frame()`.
* `is.memoised` now checks if the argument is a function.
* Testing infrastructure, full test coverage.
# Version 0.2.1
* Update to fix outstanding R CMD check issues.
# Version 0.2 (2010-11-11)
## New features
* Memoised functions now have an attribute memoised=TRUE, and
is.memoised() tests whether a function is memoised. (Contributed by
Sietse Brouwer.)
## Improvements
* Documentation is now more elaborate, and hopefully more accessible to
newcomers. Thanks to Sietse Brouwer for the verbosity.
