PowerShell RC2 - Doc Bug in Getting Started?

On page 32 of the Getting Started document that comes with RC2 the
fourth piece of code on the page seems not to relate to its preceding
text.

Doc bug?

Thanks Andrew for the information. Can you open bugs for all of these on

Hi Andrew,

Can you confirm this (qualdfold.rtf)?

----------------------------
Boolean Values and Operators
----------------------------
TRUE: Any number !=0

But:
PS C:\> -1 -eq $true
False

So it should read "Any number > 0" or there's a bug in PS

---
FALSE: Any number = 0

How many numbers equal 0? ;-)

-------------------
Foreach (Scripting)
-------------------
Expression | foreach {BEGIN{} PROCESS{} END{}}

But this doesn't work:
ls | foreach {BEGIN{} PROCESS{} END{}}

It terminates with an error, but why?

Sorry, but I don't have a Connect Account.

The correct syntax is:

ls | foreach -begin {} -process {} -end {} # using ForEach-Object cmdlet
ls | &{BEGIN {} PROCESS {} END {}} # processing in new scope
ls | .{BEGIN {} PROCESS {} END {}} # processing in current scope

The first one should be slowest, the last one should be fastest.
