print Dumper [ (MODES)[0]() ];
This statement compiles and runs as expected under Perl version 5.30.3.1 64-bit,
but fails to compile under version 5.8.9.5 32-bit (both
Strawberry). In the latter case, either of
print Dumper [ (MODES)[0]->() ];
print Dumper [ &{ (MODES)[0] } ];
will work. I haven't done a binary search to find the version at
which the quoted syntax begins to be supported
(assuming, of course, that the root cause of the failure is
a syntax enhancement).

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).
