I have a draft R7RS post ready to go.  But now that I've read a lot of the R7 
mail archive and website, I don't think the post will work as-is.  I suggest a 
shift in direction instead.

I think we ought to propose a SRFI for just curly-infix, FIRST, and then invite 
the WG to contribute if they'd like (with a pointer to the SRFI).  At which 
point the WG email is just an FYI.

After reading the R7RS discussions, I think proposing to add something in R7RS 
that is not yet implemented in many Schemes, especially an infix notation, is 
highly unlikely to work. Especially at their current stage.  Currently the R7RS 
group is working on "Small" Scheme, and they may have completed their last 
round.  They've even voted to remove caddr and friends, which are universal and 
have been in Scheme since the beginning I believe.  (How it helps portability 
by *removing* standard functions from R5RS is a mystery to me; the set of 
functions that work across R4, R5, R6, and draft R7 may be approaching the 
empty set.)

I think we'd have better luck getting a SRFI through (with an announcement 
elsewhere), then getting code into some implementations to implement the SRFI.  
*Then* we'll have more luck, methinks.  We might manage to hit a window for 
R7RS "Large", where they might be more receptive too.

Thoughts?
