Methods cannot be invoked from within lambdas or blocks

#22

class Foo def a(x, lambda)

['inside a', x].join(' ').puts()
lambda()
['exiting a', x].join(' ').puts()

def b(y)

['inside b', y].join(' ').puts()

def z

'z'.puts()
a('do something', fun do

b('ccc')

)
'exit z'.puts()

works fine, but uncommenting breaks everything changing 'class' to 'module' fixes everything

stacktrace: exception error: no function clause matching

- Title changed from class method is not seen inside a block to Methods cannot be invoked from within lambdas or blocks
Lambdas should be able to access (but not mutate) the outer scope and hidden ivar state.

I'll add support for this, with the provision that if a method is invoked which mutates the state it will crash the object.
