Perhaps you've noticed, perhaps not. The Camel book is essentially
a printed version of the
perlfunc perldoc/manpage. Which means
in particular that the
exec function is just as obscurely
documented for £26.80 as for the free machine readable version.
As to the state of the documentation, you should be aware that the evolution
of perl over the past two or three years (since 5.003) has been in great
leaps and bounds, with the number of modules in the CPAN more or less
keeping pace. The amount of documentation is awe inspiring, if some of the
individual examples of it perhaps are not.
Now that 5.6 is out, give the documentation a year or so
to catch up.
In the meantime, sites like this one can fill the gap, at least in terms of
pointing out which of the hundreds of "things" to read might be helpful
apropos of a particular problem.
