[alexandria-devel] REMOVEF and DELETEF

[Chun Tian (binghe)]

Hi, Nikodemus

Good, and thank you for so fast response, I've pulled the darcs change:

Sun Feb 24 01:10:25 CST 2008  nikodemus at random-state.net
   * fix removef and deletef not to use an inline lambda

    CLHS says the third argument to DEFINE-MODIFY-MACRO must be a  
symbol.
    Reported by Chun Tian.

Unfortunately, alexandria still cannot compile on LW 5.1, the function  
MAP-DERANGEMENTS can eval but not compile:

 > (compile 'map-derangements)

Error: Cannot compile call to SYSTEM::SET-BIT with 3 arguments -  
expected exactly 2.
   1 (abort) Return to level 0.
   2 Return to top loop level 0.

Type :b for backtrace, :c <option number> to proceed,  or :? for other  
options

Though, I think this is a bug of LW 5.1 (beta), because LW 5.0 can  
compile it well. I've already submit a bug report to LW support,  
waiting for response.

Regards,
