#345 wontfix utf8 regexp bug with underscores sjamaan Jim Ursetto
Description

Only in utf8 mode, regexp seems to have a bug with negated charsets containing underscores in either POSIX REs or SREs. I'm not sure but I think any charset with one underscore and one or more other chars is affected.

Irregex has the same problem but only when called with option 'utf8.

I'm using chicken-experimental 4.5.8 without irregex 0.8, so perhaps this bug is fixed in irregex 0.8? I haven't checked. I know this occurs back to Chicken 4.5.0 at least.

#415 fixed read-symbolic-link canonicalization of a non-link felix winkelmann Jim Ursetto
Description

In "canonicalize" mode, read-symbolic-link resolves symlinks recursively until a non-link is returned. However, if you pass it a non-link to start, it will throw an error. In my opinion, it should treat this as a base case and return the non-link instead of throwing an error.

#479 fixed bind egg should support ___blob Jim Ursetto
Description

bind supports ___byte_vector, which is deprecated. It should probably support ___blob in addition. I currently use ___byte_vector in sql-de-lite and would like to modernize that.
