Not directly, but it can be done:
<hansl>
function scalar shell_ok (void)
outfile tmpbuf --buffer
set # read the "set" variables
outfile --close
string s = strstr(tmpbuf, "shell_ok") + 10
return atof(s)
end function
</hansl>
Very clever -- but it kind of begs the introduction of a $set bundle
accessor holding all the 'set' values; so one could do stuff like
$set.shell_ok == 1 directly. OTOH, I guess one wouldn't want to have
this bundle mutable, thus (falsely?) suggesting there would be a second
way to set options, right?
