Well, you could try
[:foo :instruction | foo perform: instruction],
then call the block like
thatBlock value: someObject value: #bar.
Or, if you need the possibility of multiple arguments:
[:foo :instruction :arguments | foo perform: instruction
withArguments: arguments]
And call it like:
theOtherBlock value: someObject
value: #inject:into:
value: (Array with: 1 with: enumBlock).
These are a little simpler than using Compiler, but can allow a fair
amount of generality.
