So you are replying to a thread from April, 2009. Too bad that thread
has died, because I felt it's an important issue. What it boiled down
to back then is that the root of the problem is that you can just get
classes by name in a template. There could be special variables for
this: .classes[className], .enums[className], .statics[className]. Of
course this has security implications, like ?new has, and we should
create a few new settings of type TemplateClassLoader (like I did it
for ?new in 2.3.17).

Anyway, the solution you show is surely not good. You should at least
check the full-qualified name, and then it will still fail when
there's inheritance involved.
