Next time, make a point or ask a question that pertains to something
specific.

Yes, and also a chapter on direct manipulation of the symbol table.
Unless you think that is also a good practice to use regularly, I think
you're missing the point.
Using string eval to dynamically load a class is an obsolescent
trick. If you want to do this, you're better off using Class::MOP or
Moose.

Another very useful thing, since it enable construction of state
machines without explicit state interpretation logic (and various
other useful features).

Since I was writing about running the Perl compiler in order to create
compiled subroutines at runtime, could you perhaps enlighthen me what
the heck you are referring to?

I really, really, really don't appreciate people posting URLs to pirated

If that doesn't end you up in a bunch of killfiles, I'm not sure what
does.

on top of that he takes what he reads as gospel and doesn't think about
the consequences. or allow actual other views to penetrate. not someone
who engenders the idea of good coding practices. but of course he will
defend his views to the death without ever listening to anything else.

I have no idea if this is 'a pirated copy' or a legal one (given the
age of the book, the latter is at least not completely
impossible). You referred to 'literature'. Consequently, I used Google
to search for 'perl eval string' and this is one of the results that
came back. It is pretty ridicolous to try to hold me personally
responsible that someone from Canada (AFAIK) but something on the web
which can be found by using a search engine.

That someone completely unknown to me did something in some country
which you believe to be illegal? That's beyond pathetic. If you
consider this serious enough, get in touch with the aggrieved party
and tell them about the link so that they can take whatever action
they consider to be necessary or sensible.#

You posted an opinion. Without bothering to argue in favor of it. I
posted another opinion different from yours. This demonstrates that
there is no universal consensus on this topic, as opposed to what you
tried to suggest. I doesn't communicate anything about me.

For as long as you think that making derogatory summary statements
about others in public suits you more than trying to argue in favor of
your opinions, you cannot seriously expect to be taken seriously.

It is perfectly sensible to hold you responsible for
driving traffic to illegal content by linking to it.

I'm starting a new project that requires lots of documentation. All the
information needed to prepare the documents and dbi input is in the XML

Can anyone give me some pointers? I've searched google and the only

Ooh, how to run perl code from inside perl? I think I know that one:
{ local ( $^I, @ARGV ) = ( '', $testSuiteFile );
while ( <> ) {
s/\Q$localTestDir\E//g;
print;
}
