Why can't perl be smart enough to figure out what we mean?
We're talking about lists, the second most fundamental data structure
in the language.
If we have to resort to much magic to get these right, we're pretty much
doomed from the outset.

Does that matter? This example is fairly contrived, and anybody
actually concerned about this can always use:

I'd be in favour of forcing people to say this if they want the length
of the array.
But then, it might be that what

Hell, yes, why didn't I think of that? This is exactly the same
problem that afflicts Python's tuple syntax!

What about replacing the former syntax with:

Backtracking syntax includes:
:, ::, :::, commit, cut
I like the way the ':' looks in patterns. But I noticed I have
several niggles about a number of other aspects of the
above syntax. All the niggles are minor, individually, but
they added up to enough that I thought I'd see what the

I thought that , was actually the list constructor, much as = is the
pair constructor. (And hence
a = 1, b = 2
would be a list of pairs.)
