Really? You obviously haven't noticed Prolog, Smalltalk, Haskell, ML,
or Erlang then. And that's just the ones I can think of off the top of
my head.
* Prolog and Erlang distinguish atoms from variables by the case of
the first letter; also `_' is magical and is equivalent to a new
variable name every time you use it.
* Smalltalk distinguishes between global and local variables according
to the case of the first letter.
* Haskell distinguishes between normal functions and constructors
(both data constructors and type constructors) by the case of the
first letter, and has Prolog's `_' convention.
* ML allows a single-quote in variable names, but reserves names
beginning with a single-quote for type variables. It also has
Prolog's `_' convention.
You could add Ruby's naming rules here. Or the very very common
convention of using ALL_UPPER for symbolic constants (or
pseudo-constants as in Python). And *quite a lot* of other either
cross-language or language-specific naming conventions.
