I think it works :) $ perl import-into-warnings-notToolkit.pl
f is not init but no warning
Argument "A" isn't numeric in addition (+) at import-into-warnings-not
+Toolkit.pl line 19.
f is not a number and you're warned 0
So whatever the deal is with experimental::smartmatch it might be a bug :)
Here are all warnings forced for comparison $ perl -W import-into-warnings-notToolkit.pl
Use of uninitialized value $f in concatenation (.) or string at import
+-into-warnings-notToolkit.pl line 17.
f is not init but no warning
Argument "A" isn't numeric in addition (+) at import-into-warnings-not
+Toolkit.pl line 19.
f is not a number and you're warned 0
the code #!/usr/bin/perl --
BEGIN {
package Fake;
$INC{'Fake.pm'}=__FILE__;
use Import::Into;
sub import {
my $target = caller;
'strict'->import::into($target);
'warnings'->import::into($target);
'warnings'->unimport::out_of($target, 'uninitialized');
}
}
package Snake;
use Fake;
my $f ;
print "f is not init but no warning $f \n";
$f = 'A';
print "f is not a number @{[ 0 + $f ]}\n";
__END__

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
