The little Fortran documentation that I can find by Googling suggests that, as moritz (implicitly) points out, .EQV. is just == on Booleans. If this is correct, are you just looking to bring to Perl the syntactic beauty of Fortran :-)—or is it that you want something that does the Boolean conversion for you, so that you can write $a .EQV. $b ^** as the equivalent of $a ? $b ? 1 : 0 : $b ? 0 : 1 ^*?

Either way, as moritz says, for adding new syntax to Perl-as-it-now-is, I think that the only options are ~~syntax filters~~ (struck out as I write it so that you don't even think about it) or Devel::Declare (which worries adamk).

^* Or ($a && $b) || !($a || $b), I suppose. UPDATE: Ha, and maybe I'd like to write my own routines for addition while I'm at it. Thanks, JavaFan. :-)

UPDATE: ^** Note that this precise syntax conflicts with string concatenation, but we shouldn't be using barewords anyway.

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 or How to display code and escape characters are good places to start.
