It looks like MacRuby doesn't allow calling return in a block, which works in 1.8 and 1.9. This looks to be by design, so I'm not sure if the team wants a ticket created. Should I create a ticket?
----------------------------------------
def foo
f = Proc.new { return "return from foo from inside Proc.new" }
f.call # control leaves foo here
return "return from foo"
end
def bar
f = lambda { return "return from bar from inside lambda" }
f.call # control does not leave bar here
return "return from bar"
end
def baz
f = proc { return "return from baz from inside proc" }
f.call # control does not leave bar here in 1.8, but does in 1.9
return "return from baz"
end
puts foo
puts bar
puts baz
----------------------------------------
