While these will "work", they confuse the issue of what you are trying to accomplish.

grep is used to select items from a list.

map is used to transform one list into another.

Both take one list and return another list. In my opinion, using grep or map for tasks outside of that scope is being 'too cute', and will cost time later when maintenance time comes around. It takes more work (albeit not much) to comprehend the intent of these code blocks. Make it easier on your future-self and avoid using map and grep for this purpose.

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.
