Is the 'finally' portion of a 'try ... catch ... finally' construct even necessary? [duplicate]

• Why use try … finally without a catch clause? 7 answers

Some languages (such as C++ and early versions of PHP) don't support the finally part of a try ... catch ... finally construct. Is finally ever necessary? Because the code in it always runs, why wouldn't/shouldn't I just place that code after a try ... catch block without a finally clause? Why use one? (I'm looking for a reason/motivation for using/not using finally, not a reason to do away with 'catch' or why it's legal to do so.)
