Make sure they create readable keywords/symbols
Comment 1 by p...@hagelb.org, Apr 27, 2009
Could this be done with a regex, or should it try to confirm the name using the reader?
Comment 2 by p...@hagelb.org, Apr 27, 2009
I've implemented this in the attached patch. One thing that could be improved is that
invalid names simply raise an Exception, though it seems LispReader's ReaderException
would be more appropriate. I wasn't sure how to raise that though since it needs a
line number; it's not clear how to get the current line number.
The patch is still an improvement on the current state of things, though I'd
appreciate a tip as to how to raise the right exception.
I've also attached a patch to the test suite that ensures (symbol s) and (keyword s)
work properly in the context of invalid names. I can re-submit this to the contrib
project if that's desired if the core patch is accepted.

Last patch had a problem; used things like defn- etc. before they were defined in
core.clj. This attachment fixes that.
