We have in '*-get-{left,right}' a proposed naming convention.

Both meta-names name the same thing, according to the spec.

The spec does not provide any information on either:

	*) why an implementor should choose one name over the

	*) why a system that relies on the naming convention should
           use one name in preference to the other

So, what's the point of them?   Neither users or implementors are
benefited by the distinction.

You're saying: well, look at how they're used for particular
collection types.   

Swell -- summarizing how they are used is the job of the naming
convention spec:  a job left undone in this case.

What is the value of this apparently contentless naming convention

Why don't we also have (with the same spec):












or, in general:


I don't know if you've noticed but, you know, quite absent any srfi,
people regularly write code that uses naming conventions that "fit"
with intuitive expectations and emulate existing standard interfaces.
What value is there in a srfi that says "*-get-left implies some
intuitive expectations (but we won't try to say what those are).
