Indeed, zsh is a bit special and implements both 'which' and 'type' in 
terms of its 'whence' builtin (which has a lot of options and can tell 
you pretty much anything you would ever want to know about a command's 
disposition, check it out.) You will notice /usr/bin/which can thus give 
different results to just 'which'.

I won't try to summarize the findings only to have someone point out their idea of an exception, but it's fair to say that it's best to open a new shell to get predictable results.

You would want to start a new shell if you changed the startup files. 
Otherwise 'hash -r' is quite sufficient. Changing the value of PATH at 
runtime will do that automatically in modern shells, BTW.
