Oh, if only that were true.
I'd estimate that on average, 4 out of every 5 modules selected at random from cpan has serious shortcomings. Ranging from the crude, unidiomatic replication of built in functionality to plain old badly coded and broken crap.
Whilst the remaining 20,000+ "good" modules leaves cpan with probably the greatest concentration of freely available, quality open source software there is, the blanket acceptance and promotion of "everything cpan" by people like you, does Perl far more harm than good.
