Hi Gavin,

But remember, C++ and Java are *statically typed* languages.  I can just
check the one and only one place of variable declarations and I know all
the instance variables.  Not so with Ruby; it is fundamentally difficult
to know whether I accidentaly overwrite someone else's variable with the
same name; only bugs will reveal that... :)
