1720	"r7rs ""write"" procedure does not escape ""invalid"" symbols"	Duy Nguyen		"r7rs defines an alternative way to present a symbol that's otherwise invalid identifiers, by putting it inside `||`. This is implementation-specific in r5rs.

The problem can be seen with `(write (features))` where 64bit is not escaped (i.e. |64bit|) while it is for all the r7rs schemes I have my hands on.

This is not a problem when within chicken because both the reader and writer are in sync. I found this out because I updated chibi-snow to read `(features)` from chicken. Chibi does not like '64bit' symbol without ecaping."	defect	closed	major	6.0.0	unknown	5.2.0	fixed
