It appears that my previous email was not sent completely. Sorry for that. Here is the complete question. Hi to all, Section "3.6 symbols" of the Racket reference manual states: Interned and unreadable symbols are only weakly held ... but a symbol maay disappear when ... used as the key in a weak hash table ...". I would understand: UNINTERNED and unreadable symbols are only weakly held ... but a symbol may disappear when ... used as the key in a weak hash table ...". May be just a typo, but as I am not sure I understand the docs well, I post my question here instead of posting a bug report. Greetings, Jos
