It seems most tests are failing also.

[why]

We're totally overhauling everything right now, so head back to rev [100], please.

Is this still broken? Using the latest revision (156?)?

p sand.eval("'wtf'.upcase")

works, but

sand.eval("def blah() 'blah' end")
sand.eval("blah()")

Does not.

def self.blah works though.

I'd rather not go back to rev 100 as the change log suggests there have been security fixes since then ;
