Not too many outside R6RS, actually: only RScheme, SXM, SigScheme, UMB,
Dfsch, Foment, Chibi.

This is only available (at least at the REPL) in Racket, Chicken, SISC,
Sizzle, Vicare, IronScheme, RScheme, SXM.

That's still a lot more than provide 1+ out of the box (do any
other than Guile?).

See <http://trac.sacrideo.us/wg/wiki/PlusOneEx> for details.

You tested the wrong thing - the original question was about
1+, then 1+x was brought up, not +1x.
