This page is part of the web mail archives of SRFI 29 from before July 7th, 2015. The new archives for SRFI 29 contain all messages, not just those from before July 7th, 2015.

I agree.

Do you have any suggestions for a more appropriate name?  As to
opaqueness, the alternative is clearly to define messages individually 
into the bundle, but this has a couple of problems.  First, it doesn't
allow an implementation to optimize the bundle in any way.  If the 
messages must be added individually, then the underlying system must
be able to accept these messages and store them at any time, as opposed 
to being able to process them in bulk.  Secondly, (at a more conceptual 
level), it breaks up the idea of a set of messages defining a

I'm at a loss to think of many examples of this.  The best I can imagine 
is a network server serving clients in multiple locales.  At any rate, I 
think this is quite trivially solved by leaving current-locale alone and 
defining a new function that is able to set the current locale.  Making 
'current-locale' a parameter that is set by the Scheme system is the 
obvious way.

We can generalize the locale as being a list of symbols, from greatest 
to least significant.  (country-code language-code encoding) could be 
standardized, with any succeeding elements optional and up for

SRFI-28 was created solely to support SRFI-29.  It was kept logically 
separate in order to allow a standardization of basic format 
functionality without having to implement all of SRFI-29.  If SRFI-28 is 
rejected, then we can simply roll that specification into 29, but in 
such a case there are larger issues anyway (such as why its impossible 
to standardize on the very simple functionality of 28).
