Hi Ben,
via FaceBook via twitter I hear you've coined
BlockClosure>>#memoized. Allow me to beg you to rename it to
BlockClosure>>#once. There's a preexisting implementation of this in
>>VisualWorks by Travis Griggs called once. I hope you agree that it's
good to eliminate gratuitous incompatibilities between dialects and
that "once" is an elegant name.
#once is not the same as #memoized. #memoized returns another block
which wrap original one to perform some caching. Actually I not
understand logic behind it.But #once supposed to evaluate receiver while
#memoized creates new block.
In Pharo 6 I pushed new method #asMethodConst. Unfortunately I was not
aware about #once from VisualWorks at this time and reviewers too.
But #asMethodConst is a bit different. It is Object method instead of
Block. And it is based on AST modification.When asMethodConst is
executed it replace executing AST-node of sender with receiver which
produce new method where full message node is replaced by result as
literal.
I put mode details here

In short you can write expressions like:
10 factorial asMethodConst
