[PD] Idiomatic Pd

There are some amazing sets of abstractions being released recently,
which has served to highlight the many extant styles of patching.  I
was wondering if there was interest in establishing a set of
guidelines for patching in the vein of PEP 8 for Python; I've found
that document to be very relaxing as it is a standardized approach to
OCD.  More seriously, it greatly helps when reading other people's
code or collaborating.

The only one I have seen so far for Pd covers best practices for
layout.  I'd want to include that, but also codify naming, arguments,
common idioms, and so on.

I've begun to collect some of my practices to start things off.  I was
hoping we could all lazy-vote the document together in this thread and
I'll then compile it into a PdPedia/Pd.info document.  So, feel free
to object to or replace my propositions.

* If giving $0 as an argument to an abstraction, it is always first in
the argument list [1]
* * When possible, pass parent arguments in numeric order, like [child
$0 $1 $2 other1 other2] etc.
* Sends and Receives are written in camelCase, with "R" appended to
complementary receives (e.g. in GUIs, $0mySlider for the send and
$0mySliderR for the receive)
* When prepending $0 to a symbol, only add a "-" to separate it from
another number, like [r $0-1stSend].  Otherwise the symbol should
immediately follow, like [r $0mySend].
* When working with stereo, Left and Right pairs are written with Le
and Ri appended (to distinguish them from an R denoting "receive",

Programming recommendations
* To invert a toggle, use [== 0]
* Use the loadbang of the parent of both abstractions to initialize
two or more interdependent abstractions

[1] I think of this like emulating the "self" convention in Python

And so on...
