Ok, true, but there seems (to me) to be a difference between 
content-related characters, such as giving more descriptive names to 
variables, and syntax-related characters, such as colons and braces. I 
was thinking strictly of the language syntax and not necessarily about 
making the code quite literally more readable (with real words for 
variables instead of 'x', or 'timv' instead of 'this_is_my_variable').
