Blocks in class_eval

Ruby
1

the following works:

///// BEGIN funcmeta.rb /////
def func_meta(&b)
class_eval {
@@proc = b #guilt begins here
def test
@@proc.call
end
}
end

class Test
func_meta { puts(“test”) }
end

t = Test.new
t.test
///// END funcmeta.rb /////

any clean way to do this without resorting to a class variable?

thanks in advance, you darned helpful people!
