The motivating example can be written
aHasDot := a includes: $..
bHasDot := b includes: $..
^aHasDot = bHasDot
ifFalse: [bHasDot]
ifTrue: [aHasDot
ifTrue: [a < b]
ifFalse: [a > b]]

Note that we can already construct

and write

so we don't have to abuse the #, selector

Hello,
I have released a new version of the Pharo VM for Pharo 9 and Pharo 10.
This VM is accessible right now from Zero-Conf, updating it in the Pharo
Launcher or using the usual downloads (as described in pharo.org/download).

I care because it makes “everything is a message” a lie! And I suspect (no
proof and could be wrong) it’s an optimization that only made sense with the
hardware constraints of 40+ years ago. Arguing against prematu

I agree as a general rule, but it can get complicated

We're still not on the same page.
You seem to have some ideological objection to inlining that
I am completely failing to comprehend.
Just because a procedure call (message send) is inlined doesn't
in the least mean it *isn't* a procedure call (message send),
just as compiling a procedure call (mes
Richard,
My _concern_ with inlining is that since it is designed to short-circuit
dynamic method lookup, it is impossible to call a _different_ implementation.
That is, you lose the opportunity to have the _receiver_ decide how to respond
to the message. You may think of it as a message, but th

When the compiler inlines some methods, I would find it most surprising if it
was turned of in half the code (or just in yours :-) ). When I am reading some
code, I would rather have some consistency.
So I would just implement a whenNil: method which is a true message, and put a
