lambda vs proc; #to_ary w/ splat bug
Description
to_ary apparently gets called in edge cases when a proc has a splat argument:
good = Class.new do
def to_ary
[:bad]
end
end.new
foo = lambda { |*bar| bar.first }
foo.call(good)
foo = lambda { |bar, *baz| bar }
foo.call(good)
foo = proc { |*bar| bar.first }
foo.call(good)
foo = proc { |bar, *baz| bar }
foo.call(good)

=> "1.9.3"
good = Class.new do
?> def to_ary
[:bad]
end
end.new
