# My take on Mike's source_for method.
# (see http://pragmaticstudio.com/blog/2013/2/13/view-source-ruby-methods)
#
# (1) I named it 'src' rather than source_for (ok, I'm a lazy typer).
# (2) The edit function was broken out as a separate function.
# (3) The edit function is for emacs
# (4) If the method is not defined on the object, and the object 
#     is a class, then see if it is an instance method on the class.
#
# The fourth point allows my to say:

Today I ran a quick twitter poll asking: "What is the state of the art
in Ruby SOAP clients".

Savon (http://savonrb.com/) was by far the big winner with 29
recommendations.

Surprisingly Soap4r actually got 6 votes, but most were accompanied by
comments like "the last time I used SOAP". It was also the only entry
that got negative votes (3) with comments like "soap4r is broken and
crap by the way".
