Sean,
I agree that breaking things into smaller functions can potentially help.
Often, though, I find that a function begins by unpacking and computing a
large number of values that are all important for subsequent computations.
Dispatching these computations to helper functions would mean passing

I was just going on the information on the github wiki pages, and

Part of the confusion is that the tags are large integers, with no
"0." prefixes. I concluded that they corresponded to a jira ticket
rather than to some kind of release number.

Hi,
I'm seeking a small & idiomatic function that will take input and ensure
it's wrapped in a list. If nil, I'd like the list to be empty. If the
input is already a list, I don't want to wrap it in another list layer. So:
"hi" => ("hi")
nil=> ()
("hi") => ("hi")
(list '("hi"))
I see the rationale now, thanks. One question though, isn't it possible to
generate:
if (self && self.func) {
return self.func(self);
}
instead of
if (truth(truth(self) ? self.func : self)) {
return self.func(self);
}

In my branch the truth test is always inlined. Support for type-hints and
inference in the compiler could simplify the test when possible.

That would work for replacing a single cond surrounded by a single
