for (tie @ary, "My::Class", "some", "contents") { ... } # NOPE

does not work because for() gets a single-element list which is the tied object, not the tied array itself.

for (do { tie @ary, "My::Class", "some", "contents"; @ary }) { ... } #NOPE

does not work because for() gets an ordinary (non-magical) list of values. All the values from the tied array have been FETCH-ed. I need to iterate over the tied array so code inside the loop block and FETCH are executed once for each element, together.

tie @ary, "My::Class", "some", "contents";
for (@ary) {
   ...
}

works, but I want something more similar to:

for (wrapper(@ary)) {
   ...
}
[download]

where @ary is an ordinary array or a list of values.

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.
