I've been somewhat belatedly catching up on adding native

implementations of red docket SRFIs to Chibi, thanks to

which I found the recent errata in SRFI 133.  For SRFI 142

I did find the argument order of bitwise-if extremely strange,

but unfortunately it agreed with all existing Chibi code using

SRFI 33 bitwise-merge (since I had never updated to SRFI 60),

and I didn't bother mentioning to the list.

In the future I'll try to be a little more proactive about

implementing SRFIs before they finalize.
