An interesting consequence of "no separators allowed" is that long
identifiers are hard to read. A personal guideline that I try to
follow: if it's too hard to read without separators, it's probably too
long.

(And when you let developers create arbitrarily long identifiers, some
of them do crazy things. At work, it all started with

  Tools/Java/StringUtilities/StringTransformer.java
  Tools/Java/StringUtilities/StringCollectionTransformer.java

which are not too crazy. But they naturally spawned

  Tools/Java/StringUtilities/NullRemovalStringCollectionTransformer.java

which is only slightly less insane than

  Tools/Java/StringUtilities/StringTransformerBackedStringCollectionTransformer.java

Now when you consider the presence of

  Tools/Java/StringUtilities/ToLowerCaseStringTransformer.java

it's only natural to create

  Tools/Java/StringUtilities/ToLowerCaseStringTransformerBackedStringCollectionTransformer.java

and that, of course, demands the creation of

  Tools/Java/StringUtilities/TestToLowerCaseStringTransformerBackedStringCollectionTransformer.java

I'm not kidding! This stuff is for real! Who could make this up?)

P.S. please don't flame Java developers. The poor souls, they really
don't know any better. I actually feel sorry for them more than
anything.
