I want to use a computation cache scheme like
o = CACHECOMPUTE complex-key-expr expensive-calc-expr

expensive-calc-expr twice.
So its ugly:
_=complex-key-expr; o=cache.get(_) or
cache.setdefault(_,expensive-calc-expr)
Any ideas?
The memoize pattern can help; in
http://wiki.python.org/moin/PythonDecoratorLibrary you can see an
implementation using decorators.
