Reporter: m...@… | Owner: lsansone...@…

Priority: blocker | Milestone:
Component: MacRuby | Keywords:
-------------------------------+--------------------------------------------
MacRuby 0.5 beta 1 doesn't allow calling return in a block, which works in
1.8 and 1.9.
{{{
#!ruby
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
}}}
----------------------------------------
{{{
#!sh
$ ruby blocks.rb
return from foo from inside Proc.new
return from bar
return from baz
$ ruby19 blocks.rb
return from foo from inside Proc.new
return from bar
return from baz from inside proc
$ macruby blocks.rb
uncaught Objective-C/C++ exception...
terminate called after throwing an instance of
'RoxorReturnFromBlockException*'
