| $(P It is important to make sure that, if $(D opApply) catches any exceptions, that those | ||
| exceptions did not origin at the delegate passed to $(I opApply). Catching an exception | ||
| that escaped from the delegate would cause a condition that the user expected would terminate | ||
| the loop to not do so. |

foreachbody to both terminate the loop, and propagate outside theforeachbody."
