Greetings!
Could you give an example of these warnings, and even better some
minimal
code that generates them?
Something like this gives you warnings in apaches error.log:
#!/usr/bin/perl
#
use strict;
use warnings;
use autodie;
use CGI; # qw(:standard);
[...]
The warning says that CGI will be removed from perl and that I should
install it from cpan. I don't want to install things from cpan but the
package management of the distribution to take care of things because I
don't want to do the package management by myself.
For smartmatch:
perl -e 'print "foo" ~~ "bar";'
Smartmatch is experimental at -e line 1.
You get that for every line you're using smartmatch in.
Smartmatch works quite well; it's a really cool feature. I already know
that it's experimental. I don't need to be reminded of this 10 times
per minute in the log file while I'm trying to find a relevant message
amongst thousands of these useless warnings.
read the docs on warnings (perldoc warnings). it is easy to disable
any warning you want. note that this will be lexical so you need to
turn them off in the right location.

and even more detail can be read with perldoc perllexwarn. all about
enabling and disabling lexical warnings.
