You don't need to convert my_method to a symbol explicitly. Just pass
it on, and send will handle it on its own. That way you don't take on
responsibility for argument checking of send and if somehow send is
changed to take something that can not be represented as a symbol -
and your code gets feeded with it - the code will continue to work.
The send example may be silly because it's unlikely to change, but I
think it is a general guideline not to assume too much about the
called methods but let the called methods figure it out for
themeselves. Also I don't think this is opposed to "fail early" but
that would be open to some discussion by people more intelligent than
me.

best regards,

Brian
