Those who haven't read the article will at this point assume that Stroustrup
talks at great length about efficiency; in actual fact, he mentions it as an
aside, as his final point on a long list. Without wanting to read too much
into this, I'd suggest that he considers all the points he makes before that
to be more important.

My mention of reflection was to point out that static typing is not as
non-enabling as it's often presented. Behind which lies a serious point: a
useful chapter, that would be a strong selling point of Pickaxe2, would be
one that explains to static typers how to cope in a dynamic-typing world. I
think such things might be useful to Ruby programmers too; Smalltalk
programmers seemed more adept at coping, and their programs more
understandable (but then their distfix method syntax let them use parameter
names to give type information).
