Ha ha, and that's precisely what I love about it, in addition to the
intuitive representation and the great syntax!
In other words, the property acts a lot like a setting. Plenty of those
in LiveCode. That's also intuitive, efficient the way I use them, and
something that relates well to human experience, very easy to teach and
learn. That's a strength in my book.
I forgot to add before that numberFormat seems to have the advantage on
data type awareness. When you don't know about it, it works anyway,
using the default when you concatenate. When you desire a different
result and gain awareness, you can set it, and your concatenation code
stays the same.
With format, you must have awareness from the start. Otherwise you're
just concatenating stuff, and then the default has to cover for you. We
could call that a tie, but I look at two other points. The default
superficially looks like the way numberFormat works (the syntax is just
concatenating with no functions) and LiveCode must have that built in
anyway, unless it throws an error. Then you must change your
concatenation code to include the function.
Bottom line is the "0.0" representation is just too intuitive to beat.
Cognitive load theory or not, mark my words, that representation is
going to blow away the competition in learning. That's obvious by being
so much closer in form to the desired result. The closer things are,
generally the less work required to bridge them. You can give it fancy
names, but the underlying math will hold true regardless.
Using the property like a setting is an added plus, appealing and
intuitive for many (I'd venture to guess most) people. Some others may
prefer format. For them, it's there to use and no one is advocating that
it be removed or deprecated. And even if a new property were added to
control field display, it would probably act a lot like numberFormat.
But even that wouldn't replace the need for numberFormat itself. I think
there are so many better priorities for LiveCode's "surgeons" than
attacking the healthy tissue. There are still LC 8/9 bugs and so on that
need attention, and having to intervene on behalf of this feature takes
away a lot time from submitting those bug reports and maybe doing some
promotions and such. This is one of the good parts of LiveCode! I hope
people don't get dazzled by trends or self-destructive. I've seen that
happen before. Good feature, realize the value of what you have and hang
on to it.
