Description
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.
