They still allow you to define constants in all-caps.  The impact it
makes is not so different with defining globals as such.  Try Ruby.

The reason I used to prefer using all uppercase/capital letters, the variable
definitations would stand out similar to C style definition macros.  Variables
become extremely identifiable and comprehensible.

A text editor, such as emacs in Bash mode, can highlight variables. No
need to use any sort of naming convention.
