Issue #261 resolved
/* TODO: The library we look up here might not have the class. ex) #<(sagittarus regex)> (library (test) (export rx) (import (rnrs)) (define rx #/this won't be valid/)) The sample code will be valid for caching but reading will be invalid because we don't have any <pattern> class info anywhere. How should we treat this problem? */
This comment should be implemented since
SgClass has now
library field to get the actual binding.
