Maybe this is a clue: very few other programming languages have an "else"-case without a preceding "if true". So maybe for people versed in multiple languages the ifFalse: feels wrong?
I personally like "expr ifFalse:" better than "expr not ifTrue:". And I read "~~" as "not identical" which also has a mental "not" in it, so I prefer "== ifFalse" :)
