process ifNotNil: #terminate.
for me it means passes the symbol #terminate as argument to the method ifNotNil: If it has a more magical behavior then I do not know it.

It's exactly the same as using collection do: #something. FWIW, in 1.2 we already included the compiler changes Levente suggested to me to remove this restriction, so nil ifNotNil: #squared -> nil 4 ifNotNil: #squared -> 16. I.e. it already does what Nicolas suggested. (As per the Symbol>>#cull: thread) Cheers, Henry
The compiler uselessly insist on #ifNotNil: argument being a zero/one arg block. Thus we cannot write this xtream sentence
process ifNotNil: #terminate.
When the argument is not a block, Compiler should avoid inlining and just send a normal message.
