Well, let's try to guess some usecases.
Looking through promises I've written already, I can define following cases:
[*] a class is defined based on isvariable() call result. It is used further in
files etc, not in variables.
[*] a class is defined based on fileexists() call result which uses locally
defined variables to construct a pathname.
[*] a class is defined based on regline or strcmp for a variable passed to a
bundle as the argument, e.g. edit_line("add", "foo").
[*] a variable is defined based on previously defined (global) class(es).
[*] a variable is defined based on locally defined class(es).
As one can see from this (perhaps, incomplete) list of cases, just one case
preferes current ordering and just another one prefers reverse ordering, other
cases don't feel the difference.
Next, I've looked through 48 files which contain my current promises
collection. I must confess, I was wrong stating that I'm going to agree with
Jesse. I never use variables definition based on local classes, but there is
plenty of bundles which use classes definition based on local variables. I
remember, once I wanted the reverse ordering for something, but in a mean time
I'd found another way to achieve my goals.
So Jesse, be a pal and tell us what you're trying to do. Perhaps, there's a
much simpler way to achieve your goals.
