Subject: [ruby-talk:02948] Things I am wondering...

Just some more random questions. These are some
things I have been wondering about, and I thought
I might ask them all at once.  :)

1. Why is Dir::foreach not named Dir::each? 

2. Why are these control structures and not methods?
&& || ! and or not

3. Why are TrueClass and FalseClass separate classes?
In a way, I see the logic of it. But my instinct would
have been a single class called Boolean.

4. Why was the keyword "yield" chosen? Is this a legacy
from another language? It is not intuitive to me.

5. Like many other languages, Ruby does short-circuiting
of Boolean expressions. Other than efficiency, what is
the rationale for this? Was the other way (full 
evaluation) ever considered?


Thanks for enlightening me...
