I never write foo.@bar = xyz as that's just bad style

Most Ruby objects I have seen fail to self-encapsulate their fields. For example, it would be unusual to see something like this:

class MyObj attr_accessor :name private :name= def initialize(myname) self.name = myname end # more stuff using name or self.name instead of @name end
Usually there would be raw references to "@name" all over the place. In perl, references to $self->{"name"} are typically considered bad style. If code inside and outside the class uses different means for accessing the fields, there is more danger of typos.

But my main point was about the danger of declare-on-assignment, like this:

axxx = 1 if (rare_condition_I_forgot_to_test) axx = 2 end print axxx,"\n"
If "axx" was meant to be "axxx" there is no error message and the program does not always work as intended.
