... the tertiary conditional is an if statement(term/expression), wrapped in a do block.

The "tertiary conditional" is a conditional expression: it evaluates to one thing or else another thing. It may produce an effect like that of a  do { ... } block, but I would say it is incorrect to say it is a do-block. (Update: E.g., the  + operator produces a result like that of a do-block with some arithmetic operations in it, but it makes no sense to say it is a do-block.) What does the decompiler say?

Update: Added example. (Update: Changed example to include do-block in list.)

c:\@Work\Perl\monks>perl -wMstrict -le "my $x = 1; ;; my @ra = ( 'x', $x ? 'foo' : 'bar', 'y', do { if ($x) { 'biz' } else { 'boz' } } ); print qq{@ra}; " x foo y biz c:\@Work\Perl\monks>perl -wMstrict -MO=Deparse,-p -le "my $x = 1; ;; my @ra = ( 'x', $x ? 'foo' : 'bar', 'y', do { if ($x) { 'biz' } else { 'boz' } } ); print qq{@ra}; " BEGIN { $^W = 1; } BEGIN { $/ = "\n"; $\ = "\n"; } use strict 'refs'; (my $x = 1); (my(@ra) = ('x', ($x ? 'foo' : 'bar'), 'y', do { if ($x) { 'biz'; } else { 'boz'; } })); print("@ra"); -e syntax OK

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":

  • 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.
