I have only found it being very useful. I have never found it to be a disaster.
Have you ever used Ruby?
Not much, but I've read accounts from people who have who say that
monkey-patching doesn't scale.
Ruby on Rails has to be the most popular Ruby library/framework
PHP is popular, too.
and it adds a
lot of new functionality to existing classes in the standard library.
But just as with everything else you have to be responsible.
A language should not encourage bad behavior, nor should it make code
unreasonably difficult to reason about.
In Ruby you can
replace arbitrary methods and classes, even in the standard library. In D you
can overwrite an arbitrary piece of memory.
Not when using safe code, you can't.
