perl also has the -P option , which passes the program through the C preprocessor before exectution. So, using that option, you could use the exact same approach as you are in C++, using a #define.

#! /usr/bin/perl -P
use strict;

#define assert(exp) { if (!(exp)) { printf("assertion failed %s\n", #e
+xp); } }

my $var = 30;
assert($var == 32);
exit 0;

Output:

assertion failed 30 == 32

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
