Message Hi,

why stuff so much debugging functionality into Propel? It is bloated
as it is already. How about using debugging tools like xdebug and
Eclipse? Yes I know you can't look into what goes on inside PDO as in
what the final query string looks like after binding the
variables/parameters, but thats another story...

If you really need the lower level debugging inside Propel then add it
in a non obtrusive way by enabling dependency injection of classes
that subclass the default ones but add the debugging functionality and
then call the parent methods etc.

Cheers,

Christian
