Re: Performance question

[Ando Sonenblick <ando@...>]

True enough....

But, perhaps I'm misunderstanding something (not yet having looked into 
refs - hey, it's the weekend) but this is my understanding of them 
based on these email exchanges.

Say I have a global variable named "foo".

If I'm accessing it a lot (from C++ that is) by name, doesn't every 
access go thru a string compare look up in the global table?   And isnt 
it the case that if I make a reference to that variable and use that 
for my access, there will no longer be a string compare?

Is there still a ref look up?  Or is it a direct value (such as a ptr 
or index, etc)?

thx,
ando
