But the function time() from Time::HiRes will not
be imported. To make this binding between &main::time
and &Time::HiRes::time we have to this at compile time:
BEGIN {
eval { require Time::HiRes; import Time::HiRes qw(time) };
if($@) { warn "Unable to import Time::HiRes\n" };
}
Without the BEGIN, the binding of time to the correct function would not happen:
eval { require Time::HiRes; import Time::HiRes qw(time) };
print time()
Would produce f.exs: 976556706. While
BEGIN { eval { require Time::HiRes; import Time::HiRes qw(time) }; }
print time()
Would produce the correct time using the Time::HiRes::time function: 976556789.394509.
Autark.

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).
