Hi Akira,
You are right. I never realized this until you helped point this out.
I checked my dictionary which says that ideal can be used as a noun
and means 'a perfect example of what something should be like'; in

learning :-)

Hi Paul,
Thanks. Then I will explicitly mark this type of patches as
suggestions if there are any in the future. It is a great pleasure to
help improve the book.
