Abigail and others point that the first version is more flexible than the
second one, which is true. Reason: the first construct allows subs
. And even in languages that do, it isn't used that
often. Not every Perl programmer nowadays came by the way of C. Not by
a long shot.

I think it's worth mentioning that, right or wrong, postcodes are often
written without the space in the middle. Abigail didn't mention whether
he wanted to just match the canonical form, or match any common form.
I'll probably make it so that people can do things like
that [2 1 3 4 5] has
an odd parity, while the parity of [1 2 3 4 5] is even. But if no operation
can change the parity, there's no way of going from [2 1 3 4 5] to
[1 2 3 4 5].

Luckely, there's a 1-character length operator that is documented
to first evaluate the left operand, then the right: ,
