in reply to use vs. require in string eval?

Hello,

I think something else is going on there, if you are getting benchmarks that are that different,
with these two statements. Require and use should take up about the same amount of time,
and they do "essentially" the same thing. The main difference being of course that require's are done at runtime,
while use's are done at compile time.
Unless of course you have them wrapped in an eval, which would cause them both to be done at runtime.
