Does anyone here run Scheme with SLIME using a swank? It seems that Scheme48, MIT Scheme, Chicken Scheme, and Kawa all have robust swank implementations, with a number of others of varying quality floating around for other Scheme implementations (mostly in the form of r7rs-swank). I'm curious to here about your experience if this is the case.

Also apparently R7RS Large Tangerine Edition was released at some point, the most interesting additions to me being the R6RS numeric tower, Fixnums (SRFI 143), and Flonums (SRFI 144).
