Arithmetic Exception in 1.3

[PC]

I've been experimenting with the numeric capabilities of Clojure and I
encountered this:

Clojure 1.2.1
user=> (apply * (repeat 100 2))
1267650600228229401496703205376

Clojure 1.3.0-RC0
user=> (apply * (repeat 100 2))
ArithmeticException integer overflow
clojure.lang.Numbers.throwIntOverflow (Numbers.java:1374)

Is this really the intended behavior for version 1.3?

Auto promotion has been turned off in favor of performance. Operations
with auto-promoting behavior are available as primed functions.
Try (apply *' (repeat 100 2))

kind regards

Alternatively: (apply * (repeat 100 2N)) and allow "BigInt contagion" to work.

I see!  I'll have to go back and read up on these features.

Thanks to everyone!
