Re: How do I curtail the noise

Don't load DBD::ODBC twice. On Windows this can happen inadverently by having two statements like:

use DBD::Odbc;
use dBd::ODBC;
[download]

or , in the case of DBI, having two connection strings that are not uppercase:

dbi:ODBC:...
[download]

This isn't something I've looked into, but doesn't Perl have some mechanism to prevent loading the same module twice? I know I've seen something like this in C `#include` files -- one of the first lines is an `#ifdef` that checks to see if this file has been included already, and if so, skips the entire file. As a corollary, why would a developer want to load a module twice? Alex / talexb / Toronto "Groklaw is the open-source mentality applied to legal research" ~ Linus Torvalds	[reply] [d/l] [select]

Perl uses %INC to keep track of require'd files. On case-insensitive file systems, you can load the same file under more than one name. For example: `use Strict;` [download] loads `strict.pm` but never calls its `import` method.	[reply] [d/l] [select]

And is it useful to be able to have a `strict.pm`? I note that putting `use Carp; use carp;` [download] in a module isn't flagged by perlcritic. Should this be an error, either of style or of syntax?
