Methods cannot be invoked from within list comprehensions
Reported by Philipp Pirozhkov | February 28th, 2009 @ 07:55 AM
works fine:
class A
def bar(x)
foo(x)
def foo(y)
y
fails to load:
class A
def bar(x)
[foo(z) | z in x]
def foo(y)
y
>> load('issue.re')
.:2: variable '___instance_variables_1' is unbound
exception throw: {error,[{".",
[{2,erl_lint,
{unbound_var,'___instance_variables_1'}}]}],
[]}
in function reia_module:build/2

Ugh, another scope where issues occur accessing hidden ivar state.
Not sure of a good solution to this one either.
