Render as string containing Fluid as if it were part of the template currently being rendered.
Environment (template variables etc.) is cloned but not re-merged after rendering, which means that any and all changes in variables that happen while rendering this inline code will be destroyed after sub-rendering is finished.
Optional error message to display if error occur while rendering. If NULL, lets the error Exception pass trough (and break rendering)
If forced to FALSE, errors are not caught but rather "transmitted" as every other error would be
Optional additional/overridden namespaces, array("ns" => "Tx_MyExt_ViewHelpers")
