Re: shortcut of ":" but not /bin/true

I was thinking more upon startup, but you're right, the performance hit may not be worth it.  Maybe a lazier approach might work, though.  For example, what if this test were done when it sees that it needs to know whether the command is a built-in or not? 
 Of course, once the test is done, it won't need to do it again for future executions of the command.

Anyway, from what I understood of David's numbers, perl will build only 1% 
faster.  Is it really worth the added complexity?
