Oh, it breaks if any of the elements consists of more than one character:

% perl -le 'print"@{[split//,join q(x),split/(?<=c)/,join(q(),qw(a b c
+ d c e foo f)),2]}"'
a b c x d c e f o o f

but single spaces are fine:

% perl -le 'print"@{[split//,join q(x),split/(?<=c)/,join(q(),qw(a b c
+ d c e),q( ),q(f)),2]}"'
a b c x d c e   f

To fix this, I guess one could do something like

perl -le 'print"@{[split/\0/,join qq(\0x),split/(?<=c)/,join(qq(0),qw(
+a b c d c e foo f)),2]}"'
a b c x d c e foo f

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).
