<p class=MsoNormal><span style='color:#1F497D'>The two DLRs shipped between
IronPython and IronRuby are about 1 day apart – so they should almost be
identical. We did bump the version on the IronPython release so they’re not
actually drop-in replacements for each other.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Currently evaluation mode needs
to be flipped on and it’s a rather global option (-X:FastEval at the command
line if you want to play with it although it’s not yet exactly “fast”). It
will disable its self when it detects it can’t handle a certain construct
(currently that’s generator functions). I’m not sure what the balance will end
up being on whether we’ll have hints or if we’ll try and detect it or a
combination of both.<o:p></o:p></span></p>
