Has anyone had any success using a join in a mason line like this:
% join ",\n", map {
<% $_ %>

The map on it's own works fine, obviously, but the join is
considered contextless.
What does it get compiled to?
I know what you mean, though, it's annoying to do
% @arr = qw/foo bar fish/;
% for (0 .. $#arr) { $m->out(",\n") if $_ != 0;
<% $arr[$_] %>
% }
or
% @arr = qw/foo bar fish/;
<% shift @arr %>
% for (@arr) {
, <% $_ %>
% }
in order to separate HTML text by something.
You could maybe wrap it all in <% %>:
<% join ",\n", map { "
$_
" } qw/foo bar fish/ %>
though that's also ugly. We do something like that for
the breadcrumbs on our site:
<td class="brdcmb">
<% join(' > ', map(qq{<a href="$_->{'URI'}">$_->{'text'}</a>}, @breadcrumbs)) %>
<br /><img src="<% $SHIM %>" width="1" height="5" alt="" border="0" />
</td>
Most HTML people would freak out if they looked at that, though.
