.IP "Capture ($ref)" 4

it.
.Sp

.IX Item "CompCall ($path, @args...)"
Calls the component with \fIpath\fR and \fI\f(CI@args\fI\fR, just as with \f(CW\*(C`$m\->scomp\*(C'\fR,
with an additional coderef argument \f(CW\*(C`yield\*(C'\fR that can be invoked to generate
the content. Arguments passed to \f(CW\*(C`yield\*(C'\fR can be accessed inside the content
via \f(CW@_\fR. This is the replacement for Mason 1's Components With
Content <http://search.cpan.org/perldoc?HTML::Mason::Devel#Component_Calls_with_Content>.

Repeat the content block \fI\f(CI$count\fI\fR times. Note that the block is re-executed
each time, which may result in different content.
