since the behavior isn't consistent, I don't see why you should bother...
And just to make sure we're not sending you in the wrong direction:
Johan surely doesn't suggest turning your model objects into
WAComponents. You don't have to use #render:, and maybe you shouldn't
even call the method anything like #render, just use some method that
accepts a renderer as parameter and renders html onto it.
OTOH, speaking of the inspector: not sure about Pharo, but in VA there
is #printOn: and #debugPrintOn:, so you could also choose to implement
special behavior for inspecting/debugging purposes. This would probably
not really solve the concatenation problem, so maybe not even a relevant
note ;-)
On a side note: I have decided to not use printOn: for application
purposes if ever possible for similar reasons since I use Seaside. Too
often I had to implement different representation logic for the
application and myself as the developer. Having to go through a horribly
long list of senders of #printString, #printOn: and sometimes even
#asString in order to decide whether it's one or the other several times
was an exercise that asks for avoidance...
