Is there a method to tell me the name of the method I'm in?

This would be handy with some of my class methods for composing exception
messages...??

I think the standard thing to do is to munge Exception's backtrace:

def other_method
raise
end
def what_method
other_method
end
begin
what_method
rescue
puts $!.backtrace[0].split(" ")[1][1..-2]
end

At least that is the sort of thing I have been resorting to; if there is
a better way I'd like to know about it! :) m.

maybe you can call caller and it will tell you who you are
eg,

> def whoami
> caller[0]
>end
=> nil

=> nil

> m
=> "(irb):62:in `m'"

It Ruby 1.9, __callee__ (or __method__) will return the name of the
current method as a symbol.
