I agree explicit typing (if "typing" is the right word, I'm not even sure if perl has types as such, but I'll talk about "typing" because I think you know what I mean) is probably best. What surprised us is that we didn't think something like this :
my $var = "3";
my $otherVar = $var + 0;
Would change the typing on $var. It's as if in the past, perl created a temporary variable, a copy of $var that was treated as a number, and used that in the math without messing with $var, and now that's not the case? Or maybe the new JSON module is looking at something different to determine variable type? As you say it must be hard for JSON to figure that out, so maybe they're clutching at a different straw in that determination now. I kind of suspect that's the case, and I'd be interested to know. Is there a way to contact the JSON module author(s)?

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).
