left and right type were of the same type and not classic instances. This shortcut is dangerous for proxy types, because it means that coerce(Proxy(1), Proxy(2.1)) leaves Proxy(1) unchanged rather than turning it into Proxy(1.0). In an ever-so-slight change of semantics, I now only take the shortcut when the left and right types are of the same type and don't have the CHECKTYPES feature. It so happens that classic instances have this flag, so the shortcut is still skipped in this case (i.e. nothing changes for classic instances). Proxies also have this flag set (otherwise implementing numeric operations on proxies would become nightmarish) and this means that the shortcut is also skipped there, as desired. It so happens that int, long and float also have this flag set; that means that e.g. coerce(1, 1) will now invoke int_coerce(). This is fine: int_coerce() can deal with this, and I'm not worried about the performance; int_coerce() is only invoked when the user explicitly calls coerce(), which should be rarer than rare. |
