Yes, this is an area with low priority.

I guess when "srfi-69" loads it could provide 'srfi-90 but don't know if worth 
the trouble to support '(use srfi-90)' .

-101. I will release this but not sure how useful.

-33 has an SVN repo dir but it is empty. 33 was withdrawn anyway. The reference 
will be removed.

-7 was never supported TMK. Where is this SRFI referenced?

-47 available Chicken 3 but not 4. A "srfi-47" egg & support via the 
"array-lib" egg, which also provided SRFI 63. 

-57 available Chicken 3 but not 4.

-66 available Chicken 3 but not 4.

-72 available Chicken 3 but not 4. The "syntax-case" egg.

-85 available Chicken 3 but not 4.

-61 would export `cond'?

-62 is a reader extension only. An empty module?

-88 is a reader extension. Could export the keyword?, etc. identifiers.

-46. An empty module?
