I'm almost embarrassed to ask this, because I'm bound to be pointed to some
code that I've almost certainly read already, but here goes my ruby newbie
question:

I have an incoming stream of data in separated chunks, each having a
beginning word that defines that chunk's place in the world (how it will
respond to #to_s, etc).  Currently, I model each chunk as an object; each
has its own class.  Basically, I'm unserializing object data, but I provide
the object functionality.  I want to do off-the-stream object creation, and
so I've went and done something like:

instance_eval( "#{class_name_from_stream_chunk}.new( data_from_stream_chunk
)" )

Is this the only way to do this (by "way", I mean the code and also the
manner), and if not, the best way?
