There's not really a lot of difference between:
obj = MyClass()
obj.spam()
obj.eggs()
obj.cheese()
and
obj = MyClass().spam().eggs().cheese()
except the first takes up a lot more vertical space. Chained method calls
is idiomatic in some languages. If there is a problem with it, it is that
it doesn't make it clear that each method call is being used only for its
side-effects, rather than it being a series of distinct objects. But in
my opinion that flaw is a very minor one.
The nice thing about using an explicit method chaining call rather than
building your class to support it by default is that the initial call to
the adaptor signals that everything that follows is called only for the
side-effects.
obj = chained(MyClass()).spam().eggs().cheese()
