Thanks Leonid, Bob and others. After restarting the kernel everything worked well.I imagine something I did during the session prevented the evaluation of the code.Sorry for the noiseFg

Hi Francisco,

I can't check on 8.0.1 right now, but both v8.0 and v7.0 give the result as in the book.
I hope someone else will comment on 8.0.1.

Cheers,
Leonid

I find in Leonid's (Shiffrin) excellent book the following example (p. 122):

f[3/5,4,5,2/3]/.f[x:(_Integer|_Rational)..]:>{x}



According to the book, this returns {3/5,4,5,2/3}



However, I get (Mathematica 8.0.1, Windows 7) f[3/5,4,5,2/3]



What's wrong?

Francisco
