I had some chaining that was getting too complex due to many nil checks, so I
started to refactor using a Null Object.
However, I’m struggling a bit with the refactor due to inlining. Since #ifNil:
variants might be inlined, it seems that something like:
anObject with a long chain of messages ifNotNil: \[ :result | “…” \]
must be changed into something like:
anObject with a long chain of messages isNil ifFalse: \[ anObject with a
long chain of messages “…” \].
Obviously, I can use a temp to have:
result := anObject with a long chain of messages.
result isNil ifFalse: \[ result “…” \].
But both seem ugly and make me question using this pattern.
1. What am I missing?
2. After 40+ years of Moore’s Law, can we turn off these inlines by default?
