  Those would be good enhancements, yes.

  What kind of syntax would you consider?  I'd expect something like:

    if $USER -cmp "steve"
    if $UID  -lt 1000

  It would also be nice to have backtick support, such that
 "if `uname -a` -cmp "2.6.17" ..

  Adding such support would be easy, once the syntax was defined.

  No, I've not seen that.  Thanks.
