Not out of the box, as FreeMarker is much more a purist. However, you
could write a directive to execute BeanShell that is given as the
nested content. I'm not sure out of my head how could you access the
data-model or the variables that were created in the template, if you
could at all; that part depends on the BeanShell API.

Frankly, I think it would be better to re-think the system
architecture in those cases. FTL is a presentation language after all.
