The following works. But I've no idea how to pass params to the member

But why do you actually want to do this? If the class instance is not
important, just make a static method of this one.
class RT(object):
def Evaluate(self, code):
def generateContext():
def dropself(f):
def g(*p):
f(self)
return g
context = {}
for f in RT.__dict__:
context[f] = dropself(RT.__dict__[f])
return context
eval(code, generateContext())
def test(self):
print 'RT test'
RT().Evaluate('test()')

Is there anyway cool way you know of to generate the context at
runtime
def Evaluate(_self_,code)
exec code in GenerateContext(a)

I think exec'ing in a custom context is *more* snazzy Python. :-p

Closer.. but self.__dict__ is empty and cannot find

control.Enable="GetEnabled()" rather than what we

I thought I could eval the RHS inside the class to
get what i
wanted but alas no dice.
Well, you could do it in RT.__dict__ - but you would
have to make
test a staticmethod.
Why not maintain an explicit dictionary as a context?

Might work.

test()
a.test()
a=RT()
a.Evaluate('test()')
