I'd like to report an issue I encountered with the l3keys sub-package of l3kernel (Hope it is ok to be done here). The test code at the end produces the error

! Undefined control sequence.
<argument> \l_keys_choice_int

test code:


  colour .choice_code:n = {\l_keys_choice_tl},
  colour .generate_choices:n = {black,white},
  colour .default:n = {black},

My cat is \cat. Your cat is \cat[colour=white].

For 'out and out' bugs like this, the bug database (github.com/latex3/svn-mirror/issues) would be a good place to log things. – Joseph Wright Jun 6 '11 at 11:03

Somehow this particular variable seems to have gone missing in the code. I will of course sort that out: the fix is trivial and should be at CTAN very soon. I will also add this to the test file: this has been missed by our automated test suite.
