block in a chunk of mainline code, which is what I was hoping/expecting.
Some examples of good/bad/dangerous things to do in these <Perl></Perl> sections
would be very helpful though. I can imagine for instance that mucking around with
package declarations inside one could make life complicated.

Good stuff. Thanks for such a quick and helpful reply Stas.
The piece in the docs that had me confused was in the document
"Apache::PerlSections - Default Handler for Perl sections"
(http://perl.apache.org/docs/2.0/api/Apache/PerlSections.html#C__Apache__PerlSections__Save_).
This says:

My grasp of perl is limited, "clearing a namespace" sounds to me like something goes
away. At this point i'm not entirely clear what, but i'm glad I have an answer to work
with.
Good question. Philippe wrote this part. Philippe, could you please expand that section with some examples explaining what's exactly happening? I agree that it's quite vague and I'm not sure what did you mean there myself.
It means that if in a <Perl> section you do something like :
<Perl> $foo = "bar"; $Some::Global::var = 123; Something->init($foo); </Perl>
That once this code has been run, $foo goes away. As with the example of using
'use lib' to push tings into @INC, that's pefectly safe. Only the code (and vars)
local to the block of <Perl> gets flushed. $Some::Global::var would survive, for
instance.
