Hi, sometimes I was under the impression that hansl supports lazy evaluation of boolean expressions, and sometimes I thought that no, it doesn't. And turns out I was right because it seems to depend. Consider this:

<hansl>

clear    # neither a nor b exist
eval 1==2 && a==b    # lazy works, FALSE no matter what a or b
eval 1==1 || a==b   # lazy fails, even though it's always TRUE

</hansl>

Ah, good catch. As opposed to "&&", in the case of "||" only half of
the apparatus needed to support lazy evaluation was in place. The
other half is now added in git.
