No, that isn't a problem from a technical POV. At one Devcon,

Calvin Hsia

demonstrated a class hierarchy of 100 levels (generated

programmatically, of

course!), and that was still wicked fast. I belive the only hit

comes at compile

time, not at run time.

However, any hierarchy more than a few levels deep might be

problematic

from a desing POV. Make sure you aren't creating one-off classes, or

subclasses

which differ only in a few property settings,
