Agreed!  Regarding the guide, well, no one is going to be kicked out
of the community or have their patches burned for not adhering to the
styleguide : ).  If you would like to be creative in your lettering
you are as free as ever to do so.

But, I think many people (including myself) would rather be creative
in the functionality rather than the syntax, and for people such as
that, they might as well all do the same thing so they don't invent
even more arbitrary ways when they didn't really care to do so.

My reasoning here is that $0 is probably the most common thing to pass
to an abstraction, but abstractions have varying numbers of arguments,
so $0 will sometimes be $3, sometimes $2, sometimes $7, and that
swings my brain around.  Putting it in the first slot means that $1
gains a sort of second meaning as "my parent's $0", which I think is

And, the same memory-assistance applies to my numeric-ordering
proposition as well; I usually remember how many arguments an
abstraction has better than what order they're in, so when they're all
taken from their parent I know it will be [mychild $0 $1 $2].

That's all cool, and I think you are in the majority on that.  I think
I just took camelCase because it reminded me of Smalltalk and Cocoa,
which remind me of Pd : ).

Thanks for the comments
