It says: ..."For example, given a trait HasLegs, you could mix both
Philsophical and HasLegs"
It should say: ..."For example, given a trait HasLegs, you could mix
both Philosophical and HasLegs"

Sorry - missed the book version just now

[FIXED]

Page 215 (PDF page 247):

It says: ..."Frog still mixes in trait Philosophize,"...
It should say: ..."Frog still mixes in trait Philosophical,"...

FIXED

Page 224 (PDF page 265):

The source:

def < (that: Rational) = 
    this.numer * that.denom > that.numer * this.denom

should be:

def < (that: Rational) = 
    this.numer * that.denom < that.numer * this.denom

i.e. less than.

Kind Regards,
