Comment(by warren.weckesser):

 It is true that the erlang distribution is just a special case of the
 gamma distribution.  The requirement that the shape parameter be an
 integer is one of convention and definition; historically, the erlang
 distribution is only *defined* for integer values.  If someone wants the
 generalization, they should be explicit and use the gamma distribution.
