When dealing with complicated algorithms in languages with support for nested functions (such as Python and D) I often write huge functions (because the algorithm is complicated) but mitigate this by using nested functions to structure the complicated code.  Are huge (100+ line) functions still considered evil even if they're well-structured internally via the use of nested functions?Edit:  For those of you not familiar with Python or D, nested functions in these languages also allow access to the outer function scope.  In D this access allows mutation of variables in the outer scope.  In Python it only allows reading.  In D you can explicitly disable access to the outer scope in a nested function by declaring it static.
Are long functions acceptable if they have internal structure?
