It could be argued that in many cases its easier - especially with
multiple return statements..... When you read a book do you limit the
chapters to half a page?

People who break up code into otherwise unused functions need to
reevaluate. It breaks the read flow, causes the debugger to jump around
losing reading context.

Like all things it needs to be done sensibly.

Outlawing anything more than 16 lines or banning more than one return
statement are the action of small minded types with no bigger picture.
