Thanks for your suggestion. Your code output the following:
Ambiguous call resolved as CORE::each(), qualify as such or use & at a
+mbiguous_calls.pl line 12.
Ambiguous call resolved as CORE::chop(), qualify as such or use & at a
+mbiguous_calls.pl line 18.
dump() better written as CORE::dump() at ambiguous_calls.pl line 19.
Ambiguous call resolved as CORE::dump(), qualify as such or use & at a
+mbiguous_calls.pl line 19.
name: Ken Takakura
main::our() was called at ambiguous_calls.pl line 8.
Use of uninitialized value $person{"name"} in scalar chop at ambiguous
+_calls.pl line 18.
Abort
This result shows us that delete and our belong to "weak keywords", and each, chop and dump don't.
The following was quoted from regen/keywords.pl:
145: -chop
160: +delete
163: -dump
164: -each
261: +our
Plus (+) signs maybe mean "weak".
Your comment meant a lot to me :)

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.
