Decompile boolean lambda function inconsistency

[viralogic]

When I try to decompile a lambda function I get an assertion error:

func = lambda x: x.gpa < 20 or ((x.first_name == u'Bruce' and x.last_name == u'Fenske') or x.first_name == u'Dustin')
tree = meta.decompiler.decompile_func(func)

However, when I try to decompile this lambda function, it is successful even though they are equivalent:

func = lambda x: ((x.first_name == u'Bruce' and x.last_name == u'Fenske') or x.first_name == u'Dustin') or x.gpa > 10
tree = meta.decompiler.decompile_func(func)
print ast.dump(tree)
Lambda(args=arguments(args=[Name(id='x', ctx=Param())], vararg=None, kwarg=None, defaults=[]), body=BoolOp(op=Or(), values=[BoolOp(op=And(), values=[Compare(left=Attribute(value=Name(id='x', ctx=Load()), attr='first_name', ctx=Load()), ops=[Eq()], comparators=[u'Bruce']), Compare(left=Attribute(value=Name(id='x', ctx=Load()), attr='last_name', ctx=Load()), ops=[Eq()], comparators=[u'Fenske'])]), BoolOp(op=Or(), values=[Compare(left=Attribute(value=Name(id='x', ctx=Load()), attr='first_name', ctx=Load()), ops=[Eq()], comparators=[u'Dustin']), Compare(left=Attribute(value=Name(id='x', ctx=Load()), attr='gpa', ctx=Load()), ops=[Gt()], comparators=[Num(n=10)])])]))

From my perspective, this isn't a huge deal. I can always rewrite my lambdas in my code to use form from the successful example.

Thanks for your hard work on this library. It has proven to be very useful.
