Ruby Perofrmance
373070 [i_baseet@ho ] Why people say that Ruby is a slow language? And is there any plans to

| 373092 [steve@st ve ] It's quite possible that something has changed recently that I'm not aware

| |   + 373629 [shortcutter@] So you are claiming that Ruby is weakly typed.  It is not.  Ruby does

| |   | 373771 [shortcutter@] Dynamic typing only says something about _when_ types are evaluated.
